Question

slove the equations:3x+2y=29;5x-y=18​

Answer 1

Step-by-step explanation:

solutions:

3x+2y=29........(1)

5x-y=18........(2)

multiple the equation (2) by 2 we get,

10x-2y=36.......(3)

Sub. the equation (1)and (3)

10x-2y=36

-3x+2y=29

7x. =7

therefore X=1

placing the x=1 in equation (1),we get

3x+2y=29

3(1)+2y=29

3+2y=29

2y=29-3

2y=26

y=26/2

y=13
