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 -b + 7b = 5b - 4x + 1 for b in terms of x.
| x + 5 | |
| 1\(\frac{5}{6}\)x - \(\frac{1}{6}\) | |
| \(\frac{1}{9}\)x + \(\frac{7}{9}\) | |
| -4x - 6 |
