Question

- 3x +2y = -19
x-3y = 18
x =

y =

Answer 1

x=
`-(90)/(47)` and y=
`(288)/(47)`

Explanation:

You have to multiply both sides by 3 then add the equations vertically to eliminate a variable and you going to get -47x=90

Divide both sides of the equation by -47 e.g
`x=-(90)/(47)` substitute the given value of x into the equation -3x + 2y = 18 e.g -3x (-90/47) + 2y = 18

Answer the equation ans that's all
