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 + 7b = -6b - x - 7 for b in terms of x.
| \(\frac{2}{7}\)x + \(\frac{5}{7}\) | |
| x - \(\frac{1}{2}\) | |
| -8x - 7 | |
| 2x - \(\frac{1}{4}\) |
