.

Explanation:

.

Answer 2

`4 (1)/(2)`

Explanation:

Let's find the value of x first.

From the first sentence:

4x +13= 8

Subtract 13 from both sides:

4x= 8 -13

4x= -5

`x = - (5)/(4)`

`x = - 1 (1)/(4)`

2 times x is added to 7 → 2x +7

2x +7

`= 2( - (5)/(4) ) + 7`

`= - (5)/(2) + 7`

`= 4 (1)/(2)`
