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