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 -b + 9b = 5b - 8x - 1 for b in terms of x.
| 4x - 2 | |
| 1\(\frac{3}{13}\)x + \(\frac{1}{13}\) | |
| 3x + 1\(\frac{1}{3}\) | |
| 2\(\frac{5}{6}\)x + \(\frac{1}{6}\) |
