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 2b - 9b = 9b + 7x - 1 for b in terms of x.
| x + \(\frac{3}{10}\) | |
| -1\(\frac{1}{4}\)x + \(\frac{1}{4}\) | |
| -8x - 8 | |
| -2\(\frac{2}{7}\)x + \(\frac{1}{7}\) |
