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 + 7c = 9c + 2y - 2 for c in terms of y.
| \(\frac{5}{14}\)y + \(\frac{1}{7}\) | |
| 2y + 1 | |
| -2\(\frac{1}{3}\)y + 2\(\frac{2}{3}\) | |
| 1\(\frac{1}{4}\)y + \(\frac{3}{4}\) |
