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