46 - 4 = 3b + 3
Simplify the left side:
42 = 3b + 3
Subtract 3 from both sides:
39 = 3b
Divide both sides by 3:
b = 13
Every number has three cube roots.
The only real cube root of -64 is <em>-4</em> .
The other two cube roots of -64 are a pair of complex conjugates.
I'm too lazy to calculate them right now, and you didn't ask for them
anyway.

then just answer it together

it should say on the paper combined question like in my class it does if it does im so sorry
Answer:
y = 8.5
Step-by-step explanation:
7y - 4 = 9y +13 - 4y
First arrange to combine like terms.
7y - 4 = 9y - 4y + 13
7y - 4 = 5y + 13 Subtract 5y from each side
7y - 5y - 4 = 5y - 5y + 13
7y - 5y - 4 = 13
2y - 4 = 13 Add 4 to each side
2y - 4 + 4 = 13 + 4
2y = 13 + 4
2y = 17 Divide each side by 2
2y/2 = 17/2
y = 17/2 or 8 or 8.5
