# simultaneous linear equations

A boy started reading sometime between 3PM and 4PM and stopped reading sometime between 5PM and 6PM. He found that the hands of the watch interchanged their places. When did the boy started reading? When did he stopped reading? How long did he read? [Hint : When an hour's needle moves one hour, minute's needed moves 60 minutes.

### wich statement describes the graph 1.5x+0.2y=2.68 & 1.6 +0.3y=2.98

What you've been given is a pair of simultaneous equations, often called a system. Simultaneous just means the equations are both true at the same time. They're linear equations which means they're the sort that would be plotted as straight lines on a graph. There are two variables, x and y (and it

### use a graphical method to solve this simultaneous equation: y=x^2 and y=x+6

Plot y=x^2 and y=x+6 on the same graph. The first is a U-shaped curve sitting on the origin (0,0), the second is a straight line crossing the x axis (y=0) at x=-6 and crossing the y axis (x=0) at y=6. Where the line cuts through the U curve represents the solution to the equation x^2-x-6=0 (x^2=x+6)

### Find the y-intercept of the line that goes through the points (5,175)&(8,190).

All lines, or linear functions, can be expressed as y=ax+b, where a is the slope or gradient and b the y intercept. To find out what the linear function is we use the values for x and y of two points on the line. So we have x=5 and y=175,  and x=8 and y=190. We can find a and b by solving

### what is an equation that would have no simultaneous solutions tom6/5x-4

A parallel line would produce no simultaneous solutions. Example: y=(6/5)x which has the same gradient. The general answer is y=(6/5)x+a where a is a constant.

### find x and y :10/x+y + 2/x-y=4 and 15/x+y - 5/x-y=-2

10/(x+y)+2/(x-y)=4, 15/(x+y)-5/(x-y)=-2. There are several ways of solving: try this one: let X=1/(x+y) and Y=1/(x-y): 10X+2Y=4, which reduces to 5X+Y=2; 15X-5Y=-2, substituting the new variables. We arrive at simultaneous linear equations. So, multiplying the first equation by 3,

### use the graphical method to solve each of the following pairs of equations, y-3x=11, 5x+30=4y

These are linear equations so their graphs are straight lines. The easiest way to draw them is to identify for each equation where the line cuts across the axes. The cut on the y axis is given by setting x=0 in each equation, on the x axis it's where y=0. Take the first equation. When x=0 y=11,

### Solve the following linear programming problem graphically using the corner-point method

Draw the graphs of X+2Y=8 and 5X+4Y=20. The corner point is where the lines cross, and this can be found by solving the two line equations as simultaneous equations. If we double eqn 1 and subtract from eqn 2 we get 3X=4 so X=4/3 and therefore, by substituting for X in either eqn we get Y=10/3. The
