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