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 -8b + 9b = 6b + 6y - 1 for b in terms of y.
| -\(\frac{3}{10}\)y + \(\frac{2}{5}\) | |
| -2y - 1 | |
| \(\frac{3}{14}\)y + \(\frac{1}{14}\) | |
| y + \(\frac{2}{3}\) |
