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 + 9b = 2b - 8x + 4 for b in terms of x.
| -x - \(\frac{6}{7}\) | |
| -4\(\frac{1}{4}\)x + 1 | |
| -\(\frac{1}{4}\)x + 2\(\frac{1}{4}\) | |
| -2\(\frac{1}{2}\)x + 3\(\frac{1}{2}\) |
