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