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 -3b + 7b = 9b + 3x + 2 for b in terms of x.
| -2\(\frac{3}{4}\)x + 2 | |
| -\(\frac{1}{11}\)x + \(\frac{1}{11}\) | |
| \(\frac{1}{3}\)x - \(\frac{1}{6}\) | |
| x + 8 |
