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 9b + 8b = 4b - 7x + 8 for b in terms of x.
| -4x + 5 | |
| -3x + 1\(\frac{3}{5}\) | |
| -\(\frac{3}{11}\)x + \(\frac{5}{11}\) | |
| x - \(\frac{3}{5}\) |
