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 - 4c = 8c - 4y + 6 for c in terms of y.
| 4\(\frac{2}{3}\)y + 2\(\frac{1}{3}\) | |
| 1\(\frac{6}{7}\)y - \(\frac{5}{7}\) | |
| y - \(\frac{6}{13}\) | |
| 2\(\frac{5}{6}\)y - 1\(\frac{1}{2}\) |
