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