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 5b + 8b = b - 4x + 7 for b in terms of x.
| 1\(\frac{3}{8}\)x + \(\frac{1}{2}\) | |
| -1\(\frac{1}{3}\)x - \(\frac{8}{9}\) | |
| -3x + 1\(\frac{3}{4}\) | |
| \(\frac{11}{12}\)x + \(\frac{5}{12}\) |
