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 = 6b + 7y - 4 for b in terms of y.
| -\(\frac{6}{11}\)y - \(\frac{8}{11}\) | |
| -\(\frac{1}{15}\)y - \(\frac{3}{5}\) | |
| 2y + 1 | |
| 11y - 4 |
