Please help and show all the steps! :) Thx!!

1. 7x + 5(-3x - 15) = 13
- what is the value of x?

2. 4x + 7(x + 17) = 185
- what is the value of x?

Respuesta :

mumsy
7x+5(-3x-15)=13
open the parantheses
7x-15x-75=13
-8x=75+13
-8x=88
x=-(88/8)=-11

second problem
4x+7x+119=185  I multiplied 7 by the paranthesis
11x=185-119
11x=66
x=66/11
x=6
