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