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 -b - 2b = -2b + 7y + 8 for b in terms of y.
| \(\frac{1}{8}\)y - \(\frac{5}{8}\) | |
| -\(\frac{6}{7}\)y + 1\(\frac{2}{7}\) | |
| -\(\frac{7}{16}\)y + \(\frac{1}{16}\) | |
| 9y + 8 |
