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 - 3c = 6c - 3y + 3 for c in terms of y.
| y + 3 | |
| -1\(\frac{5}{7}\)y + 1 | |
| \(\frac{3}{14}\)y - \(\frac{1}{14}\) | |
| -4y - \(\frac{1}{2}\) |
