x= -35/11
1) distribute, -9x -63x = 13x+7
2) put like terms on the same side of parentheses, -9x -13x= 7+63
3) combine like terms, -22x = 70
4) solve for x, x= -70/22
5) simplify, x= -35/11
The solution for t
4 = 2t + 8
4 + (-8) = 2t + 8 + (-8)
-4 = 2t
-4 / 2 = 2t / 2
-2 = t
t = -2

Step-by-step explanation:
I have answered this question before.
Given:
Bob has three kids whose ages has the product of 72. I will only be able to give you a set of 3 numbers to represent the ages. Had the sum of the ages been given, the specific ages would be provided.
I just did a prime factorization of 72.
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
1 x 2 x 2 x 2 x 3 x 3 = 72 ⇒ 2³ x 3²
There are a lot of possible combinations, here are a few.
1 x 8 x 9 = 72 ⇒ 1 + 8 + 9 = 18
1 x 4 x 18 = 72 ⇒ 1 + 4 + 18 = 23
<span>2 x 4 x 9 = 72 ⇒ 2 + 4 + 9 = 15</span>
