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 = -b + 7y - 7 for b in terms of y.
| \(\frac{1}{2}\)y + 1\(\frac{3}{4}\) | |
| \(\frac{1}{7}\)y - \(\frac{1}{7}\) | |
| -1\(\frac{1}{11}\)y + \(\frac{5}{11}\) | |
| -\(\frac{7}{12}\)y + \(\frac{5}{12}\) |
