3z+6(z-5)=-48

3 z + 6 (z - 5) = - 48

z = - 2

Solution steps

3 z + 6 (z - 5) = - 48

Expand

6 (z - 5) : 6 z - 30

3 z + 6 z - 30 = - 48

Add similar elements:

3 z + 6 z = 9 z

9 z - 30 = - 48

Move

30

to the right side

9 z = - 18

Divide both sides by

9

z = - 2

2 (x + 7) = 9 x

m + 16 = 20

\frac{1}{3} c - 7 = 1

4 - (y - 3) = 3 (y + 1) - 4 (1 - y)

3 x + 15 = 21
