How exactly do i do this ?
1 answer:
4x + 2y = 8
4(-2) + 2y = 8
-8 + 2y = 8
+ 8 + 8
2y = 16
2 2
y = 8
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
- 4 - 4
2y = 4
2 2
y = 2
4x + 2y = 8
4(3) + 2y = 8
12 + 2y = 8
- 12 - 12
2y = -4
2 2
y = -2

Step-by-step explanation:
The answer is C.) x = 7; x = -6
Subtract a from both sides of the equation.
b=−a+14

2.4 x 100 = 240%
I think it might be false, I could be wrong though.
Hopefully that helped! :)
