Question

x + y = -4
-3x + 2y = 2

Answer 1

Use the substitution method to solve this.

x+y = -4 is a given
So

x = -4 - y

Now put this x's value in the second equation and then solve for y.

When you get y, put y's value into any of the 2 equations to get x.

Understood? :)

Answer 2

help this graphic don't know how to find the two numbers ( )

Answer 3

STEP BY STEP
1. make x in the equation x + y =4 subject of formular, that is x= ?????

2 . for the value x in -3x + 2y =2, do not write x, SUBSTITUTE x with the answer you found in the first step.

thus -3( ????) + 2y =2

3. solve for y

when you get your y, take it to the equation x + y = 4, and instead of y, put the value of y.
You have got your x.

your answer will be (x,y)
