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 -8b + 7b = -b - 6x + 7 for b in terms of x.
| -\(\frac{6}{7}\)x + \(\frac{4}{7}\) | |
| 1\(\frac{6}{7}\)x - 1 | |
| x + 1 | |
| -\(\frac{2}{13}\)x - \(\frac{6}{13}\) |
