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