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 + 8c = 2c - 2z + 2 for c in terms of z.
| -\(\frac{3}{4}\)z + 1 | |
| 1\(\frac{3}{7}\)z - \(\frac{2}{7}\) | |
| -2\(\frac{1}{2}\)z + 2 | |
| -2\(\frac{1}{4}\)z - 1\(\frac{1}{4}\) |
