Question

1/4(z +3z)+ 7=−z + 1 please help with this ive been stuck

Answer 1

First, simplify the parenthesis. You’ll get:
1/4(4z)+7=-z+1

Then multiply 1/4 by 4z. You’ll get:
z+7=-z+1

Love like terms to the same side. I wanted to have the variable positive on time, so I moved variables to the left and constants to the right. You’ll get:
2z=-6

Divide both sides by 2. You’ll get :
z=-3
