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 + = 4b + y - 7 for b in terms of y.
| -15y - 9 | |
| -y + \(\frac{9}{11}\) | |
| y - 7 | |
| -2\(\frac{1}{8}\)y + \(\frac{1}{2}\) |
