Answer:
The answer to your question is -3, 7
Step-by-step explanation:
Data
x + y = 4 ------------ Equation l
7x + 9y = 42 ----------- Equation ll
Process
1.- Solve the system by elimination
- Multiply equation l by -7
-7x - 7y = - 28
7x+9y = 42
2.- Simplify
0 + 2y = 14
3.- Solve for y
y = 14/2
y = 7
4.- Substitute y in equation l to find x
x + 7 = 4
Solve for x
x = 4 - 7
x = -3

Answer:
x = 3
Step-by-step explanation:
2y = 2x - 8
2(-2x + 5) = 2x -8
-4x + 10 = 2x - 8
+4x +4x
10 = 6x - 8
+8 +8
18 = 6x
divide both sides by 6
x = 3
