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 -2c - 5c = -4c + 7z - 8 for c in terms of z.
| -2z + 2\(\frac{2}{3}\) | |
| -\(\frac{3}{17}\)z + \(\frac{3}{17}\) | |
| 1\(\frac{1}{4}\)z + \(\frac{1}{2}\) | |
| 6z - 4 |
