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 - 8b = -5b + 9x + 1 for b in terms of x.
| 1\(\frac{8}{9}\)x + \(\frac{1}{9}\) | |
| \(\frac{3}{8}\)x - \(\frac{7}{8}\) | |
| -1\(\frac{1}{15}\)x + \(\frac{7}{15}\) | |
| -3\(\frac{1}{3}\)x - 1\(\frac{1}{3}\) |
