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 + 9b = -7b + 7y + 6 for b in terms of y.
| y - 1\(\frac{1}{5}\) | |
| \(\frac{1}{2}\)y + 2 | |
| -\(\frac{3}{4}\)y - \(\frac{1}{2}\) | |
| -y + 3 |
