First, simplify the equation by distributing -7 to the terms inside the parentheses:
70 = -7*(-2) - 7*(-2z)
70 = 14 + 14z
Next, isolate the variable term by subtracting 14 from both sides:
70 - 14 = 14z
56 = 14z
Finally, divide both sides by 14 to solve for z:
56/14 = z
z = 4
Therefore, the solution to the equation is z = 4.
Solve the equation.
70 = –7(–2 – 2z)
