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 -b + 4b = -5b - 9y + 4 for b in terms of y.
| -3\(\frac{1}{4}\)y + 1 | |
| 5y - 4 | |
| \(\frac{4}{15}\)y - \(\frac{7}{15}\) | |
| \(\frac{2}{3}\)y - 1 |
