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