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 - 7b = b + 5y - 3 for b in terms of y.
| \(\frac{10}{11}\)y - \(\frac{4}{11}\) | |
| \(\frac{1}{4}\)y + \(\frac{1}{4}\) | |
| 12y - 3 | |
| -9y + 1 |
