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 5c + 8c = 2c + 2z - 3 for c in terms of z.
| 1\(\frac{3}{8}\)z - 1\(\frac{1}{8}\) | |
| -2z - 1 | |
| 4z - 2\(\frac{2}{3}\) | |
| -\(\frac{1}{13}\)z - \(\frac{1}{13}\) |
