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