3x-2-x=7-x
3x-2-x=7-x
3x - x + x = 7 + 2
3x = 9
x = ?
Given:
3x-2-x=7-x
Add x to each side to get
3x-2=7
Add 2 to each side to get
3x=9
Solve for x.
To solve the equation 3x - 2 - x = 7 - x, we can follow these steps:
Step 1: Combine like terms on each side of the equation:
On the left side, we have 3x - x = 2x.
On the right side, we have -2 - 7 = -9.
So the equation simplifies to 2x = -9.
Step 2: Solve for x:
To isolate x, we need to get rid of the 2 coefficient on the left side. We can do this by dividing both sides of the equation by 2:
(2x)/2 = (-9)/2.
This simplifies to x = -9/2 or x = -4.5.
Thus, the solution to the equation 3x - 2 - x = 7 - x is x = -4.5.
