Answer:
x = - 2
y = 7
Step-by-step explanation:
4x - 2y = - 20
Now substitute - 3x for y.
4x - 2(-3x) = -20 combine the xs in the brackets
4x + 6x = - 20 Make the addition
10x = - 20 Divide by 10
x = - 20/10 Do the division
x = - 2
===============
3x - 2y = - 20 Put - 2 in for x
3(-2) - 2y = - 20 remove the brackets
- 6 - 2y = - 20 Add 6 to both sides
-2y = - 20 + 6 Combine
-2y = - 14 Divide by - 2
y = - 14/-2
y = 7
