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 -8b - 4b = -9b + 9x + 5 for b in terms of x.
| 13x + 5 | |
| \(\frac{8}{9}\)x - 1 | |
| \(\frac{3}{7}\)x + 1\(\frac{1}{7}\) | |
| -4\(\frac{1}{2}\)x + \(\frac{1}{2}\) |
