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