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