Answer:
Step-by-step explanation:
-3 would be the correct answer
Step-by-step explanation:
solve simultaneously
subtract the 2 equations like you subtract pure numbers from each other.
5x + 2y = 12
3x + 2y = 8
5x - 3x +2y - 2y = 12 - 8
2x = 4
x = 2
alternatively...
3x + 2y = 8
5x + 2y = 12
-2x = -4
x = 2.
Answer:
