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 -9b + 8b = 5b + 5y - 6 for b in terms of y.
| 1\(\frac{5}{8}\)y - \(\frac{3}{4}\) | |
| -\(\frac{3}{7}\)y + 1 | |
| \(\frac{3}{14}\)y + \(\frac{3}{7}\) | |
| 8y - 2 |
