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 - 2b = -8b + 9x + 3 for b in terms of x.
| -\(\frac{1}{16}\)x + \(\frac{9}{16}\) | |
| \(\frac{2}{5}\)x - \(\frac{4}{5}\) | |
| 11x + 3 | |
| -13x + 9 |
