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 8b - 3b = 4b + 2x - 5 for b in terms of x.
| -\(\frac{6}{7}\)x + 1\(\frac{2}{7}\) | |
| -5x + 5 | |
| 4\(\frac{2}{3}\)x + 1\(\frac{2}{3}\) | |
| 1\(\frac{1}{4}\)x - 1\(\frac{1}{4}\) |
