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 + 9b = 3b + y + 1 for b in terms of y.
| -17y - 1 | |
| 1\(\frac{3}{4}\)y - \(\frac{3}{4}\) | |
| -1\(\frac{1}{4}\)y + 1\(\frac{1}{2}\) | |
| 8y - 1 |
