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 7b + 8b = -9b + 9x + 1 for b in terms of x.
| x - \(\frac{9}{11}\) | |
| \(\frac{1}{16}\)x + \(\frac{1}{16}\) | |
| 2\(\frac{1}{4}\)x - 1\(\frac{3}{4}\) | |
| -2\(\frac{1}{2}\)x - 4\(\frac{1}{2}\) |
