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 + 3c = -8c - 7z - 4 for c in terms of z.
| -1\(\frac{2}{3}\)z - \(\frac{2}{3}\) | |
| 4z - 1 | |
| -\(\frac{2}{15}\)z + \(\frac{1}{15}\) | |
| -10z + 8 |
