When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -5c + 5c = -8c - 8z + 8 for c in terms of z.
| -6z - 2\(\frac{1}{2}\) | |
| 2z - 1 | |
| -2\(\frac{1}{2}\)z + 4 | |
| -4\(\frac{1}{3}\)z + 2\(\frac{2}{3}\) |
