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 = 8b + 3x - 7 for b in terms of x.
| -2x + 2\(\frac{2}{3}\) | |
| \(\frac{3}{11}\)x + \(\frac{1}{11}\) | |
| -2x - \(\frac{1}{4}\) | |
| \(\frac{1}{4}\)x + 1\(\frac{3}{4}\) |
