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 - b = 4b - 7x - 1 for b in terms of x.
| -4\(\frac{2}{3}\)x + 1\(\frac{1}{3}\) | |
| 3x + 4 | |
| 1\(\frac{1}{5}\)x + \(\frac{1}{5}\) | |
| 3\(\frac{2}{3}\)x + 2\(\frac{1}{3}\) |
