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 + 9b = -7b - 8x + 8 for b in terms of x.
| 2\(\frac{1}{3}\)x + \(\frac{1}{3}\) | |
| \(\frac{2}{7}\)x + 1\(\frac{1}{7}\) | |
| -\(\frac{1}{4}\)x + 1\(\frac{1}{4}\) | |
| -1\(\frac{3}{14}\)x + \(\frac{4}{7}\) |
