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