Question

I’m in algebra 1 and need help with #6?

Answer 1

Answer: 28

Explanation:

First, we will write what the first line of text represents:

3x + 5 = 7

Then, we will solve:

3x + 5 = 7

3x = 2

x =
`(2)/(3)`

Lastly, we will substitute this value of x into the expression and simplify:

12x + 20

12(
`(2)/(3)`) + 20

8 + 20

28
