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