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 -2b - 2b = 4b + 7x - 2 for b in terms of x.
| -1\(\frac{1}{2}\)x + \(\frac{1}{3}\) | |
| -\(\frac{7}{8}\)x - \(\frac{3}{16}\) | |
| 2\(\frac{1}{2}\)x + 4 | |
| \(\frac{1}{2}\)x + 1\(\frac{1}{3}\) |
