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 9b + 9b = 5b + 6x + 4 for b in terms of x.
| -\(\frac{3}{4}\)x + 1 | |
| 9x - 6 | |
| -10x + 9 | |
| 15x + 2 |
