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 -6b - 3b = 3b - y - 7 for b in terms of y.
| -2\(\frac{5}{6}\)y - \(\frac{5}{6}\) | |
| -\(\frac{2}{9}\)y + \(\frac{7}{9}\) | |
| 1\(\frac{1}{4}\)y - \(\frac{1}{4}\) | |
| \(\frac{8}{13}\)y + \(\frac{1}{13}\) |
