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 = 3c - 6y + 4 for c in terms of y.
| -3y - 2\(\frac{1}{4}\) | |
| -1\(\frac{1}{4}\)y + 1 | |
| 11y - 5 | |
| -y - 4 |
