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 -5b + 8b = 5b + 3y - 9 for b in terms of y.
| \(\frac{1}{2}\)y + \(\frac{9}{10}\) | |
| -\(\frac{3}{5}\)y - \(\frac{9}{10}\) | |
| -\(\frac{5}{8}\)y + 1 | |
| \(\frac{1}{2}\)y + 2\(\frac{1}{4}\) |
