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 -4b + 10b = 9b - 9x - 8 for b in terms of x.
| 10x + 7 | |
| 1\(\frac{6}{13}\)x + \(\frac{8}{13}\) | |
| 2\(\frac{1}{3}\)x + 2\(\frac{2}{3}\) | |
| -2x - \(\frac{1}{3}\) |
