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