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 - 9z - 6 for c in terms of z.
| \(\frac{6}{7}\)z + 1\(\frac{1}{7}\) | |
| -\(\frac{3}{7}\)z - \(\frac{6}{7}\) | |
| 4z + 2\(\frac{1}{2}\) | |
| -\(\frac{3}{4}\)z + 1\(\frac{3}{4}\) |
