z = 4
z = 4
z = –28
z = –28
z = –112
z = –112
z = 784
To solve for z, we can first simplify the equation:
70 = -7(-2 - 2z)
Multiply -7 by each term inside the parentheses:
70 = 14 + 14z
Subtract 14 from both sides:
56 = 14z
Divide both sides by 14:
z = 4
Therefore, the solution is z = 4.
To solve the equation 70 = –7(–2 – 2z), we can follow these steps:
1. Distribute -7 to the terms inside the parentheses:
70 = -7 * -2 - 7 * 2z
2. Simplify the equation:
70 = 14 + 14z
3. Subtract 14 from both sides of the equation:
70 - 14 = 14z
4. Simplify the left side of the equation:
56 = 14z
5. Divide both sides of the equation by 14:
56/14 = z
6. Simplify the right side of the equation:
4 = z
Therefore, the solution to the equation 70 = –7(–2 – 2z) is z = 4.
