Using a graph solve for x and y If 12x3y 24 And 6x3y15 Using

Solution

We have 12x-3y=24

& 6x + 3y=15

To plot a line we have to find the x & y intercept of two equation

For first x- intercept 2 & y:8

For second x-intercept=5/3 & y:5

To find solution we have to solve this equation as follows

Adding this two equation we get

18x=39

I.e. x=39/18=13/6

Put value of x in

6x+3y=15; we get

6*(13/6)+3y=15

13+3y=15

y=2/3
