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 7c - 2c = -2c + 7y + 8 for c in terms of y.
| 2\(\frac{1}{2}\)y + \(\frac{1}{4}\) | |
| -\(\frac{3}{10}\)y + \(\frac{3}{10}\) | |
| 1\(\frac{1}{9}\)y - \(\frac{8}{9}\) | |
| y + \(\frac{8}{9}\) |
