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 -2b + 2b = -3b + 2x - 7 for b in terms of x.
| x - 7 | |
| -7\(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| 15x - 9 | |
| -\(\frac{6}{11}\)x - \(\frac{5}{11}\) |
