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 + 4b = -3b + 9x + 2 for b in terms of x.
| -2\(\frac{3}{7}\)x - 1 | |
| 2\(\frac{3}{5}\)x + 1\(\frac{4}{5}\) | |
| x + 2 | |
| \(\frac{1}{2}\)x + \(\frac{1}{5}\) |
