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 - 2b = b + x + 8 for b in terms of x.
| \(\frac{3}{8}\)x + 1 | |
| -4x + 8 | |
| -12x + 7 | |
| \(\frac{4}{15}\)x + \(\frac{1}{15}\) |
