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 + 2y + 2 for c in terms of y.
| 3\(\frac{1}{5}\)y + 1\(\frac{3}{5}\) | |
| -4y - 1 | |
| \(\frac{6}{7}\)y - \(\frac{2}{7}\) | |
| y - 7 |
