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