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 + 5c = -4c - 9y - 8 for c in terms of y.
| -\(\frac{6}{7}\)y + \(\frac{3}{7}\) | |
| y - 2\(\frac{1}{3}\) | |
| 4\(\frac{2}{3}\)y + 2\(\frac{2}{3}\) | |
| 4\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) |
