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