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 -6c - 4c = -2c - 5y - 7 for c in terms of y.
| y - 1 | |
| \(\frac{1}{4}\)y + 1\(\frac{3}{4}\) | |
| \(\frac{5}{9}\)y - \(\frac{1}{3}\) | |
| \(\frac{2}{7}\)y - \(\frac{2}{7}\) |
