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 -5b + 9b = -7b - 2x + 7 for b in terms of x.
| -10x - 7 | |
| -5\(\frac{1}{2}\)x + 3\(\frac{1}{2}\) | |
| 2x - 2\(\frac{1}{3}\) | |
| x + \(\frac{7}{17}\) |
