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 -2c - 7c = 2c - 7y + 5 for c in terms of y.
| y - 1\(\frac{1}{4}\) | |
| -\(\frac{1}{12}\)y + \(\frac{3}{4}\) | |
| \(\frac{7}{11}\)y - \(\frac{5}{11}\) | |
| -2\(\frac{1}{2}\)y + 1 |
