To solve the equation 7x - 3 - 4x = 9, we need to combine like terms and isolate the variable x.
Combining like terms, we have:
(7x - 4x) - 3 = 9
3x - 3 = 9
Next, we need to isolate the x term. To do this, we add 3 to both sides of the equation:
3x - 3 + 3 = 9 + 3
3x = 12
Now, to solve for x, we divide both sides by 3:
3x/3 = 12/3
x = 4
Therefore, the solution is x = 4.
Solve the equation. 7x - 3 - 4x = 9
