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 7b - 4b = 8b - 7y + 5 for b in terms of y.
| \(\frac{2}{7}\)y - 1\(\frac{1}{7}\) | |
| -2\(\frac{3}{5}\)y - 1 | |
| \(\frac{7}{9}\)y - \(\frac{8}{9}\) | |
| 3y - 5 |
