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 + 8c = 5c - 6y + 7 for c in terms of y.
| \(\frac{2}{13}\)y - \(\frac{1}{13}\) | |
| 7y + 6 | |
| 2y - 1 | |
| 2y + 6 |
