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