Question

-7(z - 6) = -70 * answer

Answer 1

Answer:

the answer is

z -6 =10

z = 16

Answer 2

Answer:

z = 16

Step-by-step explanation:

Simplifying

-7(z + -6) = -70

Reorder the terms:

-7(-6 + z) = -70

(-6 * -7 + z * -7) = -70

(42 + -7z) = -70

Solving

42 + -7z = -70

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '-42' to each side of the equation.

42 + -42 + -7z = -70 + -42

Combine like terms: 42 + -42 = 0

0 + -7z = -70 + -42

-7z = -70 + -42

Combine like terms: -70 + -42 = -112

-7z = -112

Divide each side by '-7'.

z = 16

Simplifying

z = 16
