To solve the equation, we need to distribute the -7 to both terms inside the parentheses:
70 = -7(-2) - 7(2z)
This simplifies to:
70 = 14 + (-14z)
Combining like terms, we get:
70 = 14 - 14z
Subtracting 14 from both sides, we have:
70 - 14 = -14z
56 = -14z
To solve for z, we can divide both sides by -14:
56 / -14 = -14z / -14
-4 = z
Therefore, the solution is z = -4.
olve the following equation.
70 = –7(–2 – 2z)
