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 - 6b = -9b + 7y - 7 for b in terms of y.
| -2y + 3 | |
| \(\frac{13}{16}\)y - \(\frac{7}{16}\) | |
| -\(\frac{1}{3}\)y + \(\frac{1}{3}\) | |
| \(\frac{7}{10}\)y + \(\frac{1}{5}\) |
