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