Answer: x=4 ; y=<u> -4</u>
3
Step-by-step explanation:
2x + y = -4
.(-3)
2x + 3y = 4
-6x-3y=12
<u>2x + 3y = 4</u>
4x=16
x= <u>16</u>
4
x=4
2x + 3y = 4
2.4+3y=4
8+3y=4
3y= -8+4
y=<u> -4</u>
3
to find the area of a rectangle is LxW=A

L = 7
W = x-8
A = 42
7 * x-8 = 42
7x-56= 42
solve for X
Answer: 64
