Yes it makes it a true statement because if my math is correct it will add up and the negative is not canceled. That’s only with multiplication
4x + 2y = 20
3x - y = 10
Multiplying second equation by 2.
6x - 2y = 20
Adding to the first,
10x = 40
x = 4
y = 3x - 10 = 3(4) - 10 = 2
Answer: (4, 2)
Check:
4(4) + 2(2) = 16+4 = 20, good
3(4) - 2 = 12 - 2 = 10, good
Answer:
