70 = –7(–2 – 2z)

Answer 1

To solve the equation, we will first simplify the expression on the right side:

–7(–2 – 2z) = –7(-2) – 7(2z) = 14 + 14z

So the equation can be rewritten as:

70 = 14 + 14z

Next, we will isolate the variable by subtracting 14 from both sides of the equation:

70 - 14 = 14 + 14z - 14

Simplifying the left side gives:

56 = 14z

To solve for z, we will divide both sides of the equation by 14:

56/14 = 14z/14

4 = z

Therefore, the solution to the equation is z = 4.
