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 -6b + 4b = 9b + 9y + 1 for b in terms of y.
| -y + 1 | |
| 11y + 8 | |
| 4y - 2 | |
| -\(\frac{1}{3}\)y - \(\frac{1}{15}\) |
