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