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 - 6c = 5c - 3y + 1 for c in terms of y.
| -6\(\frac{1}{2}\)y + 4 | |
| -1\(\frac{1}{7}\)y - 1\(\frac{2}{7}\) | |
| -\(\frac{3}{10}\)y - \(\frac{1}{10}\) | |
| 3y + 1\(\frac{3}{4}\) |
