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 7b - 6b = -b + 7x - 5 for b in terms of x.
| 15x + 8 | |
| -\(\frac{3}{7}\)x - \(\frac{1}{7}\) | |
| 1\(\frac{5}{8}\)x - \(\frac{5}{8}\) | |
| x - 1\(\frac{1}{2}\) |
