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 -4b + 4b = 9b + 2x - 1 for b in terms of x.
| \(\frac{2}{13}\)x + \(\frac{1}{13}\) | |
| 10x + 7 | |
| -1\(\frac{1}{4}\)x + 1 | |
| \(\frac{1}{2}\)x + \(\frac{1}{4}\) |
