Answer:
C: 4
Step-by-step explanation:
4x+3=6x-5
Add five to both sides
4x+8=6x
Subtract both sides by 4x
8=2x
Divide both sides by 2
X=4
The answer is in the attachment
If each face has an area of 4 than the side lengths are 2, because area is b•h and 2•2 is 4. Now, volume is length•width•height. All of these will be two because sides are the same in a cube. 2•2•2 is 8, which is your answer
The first sentence → x - 2y = -1
the second one → 3x - 2y = -3
multiply the first one by -1
you can get → -x + 2y = 1
plus two sentences together
you can get → 2x = -2
so you are able to know that x = -1
and y = 0
