What value(s) of x make the following equation true?<br> 2x - 6 = 3x + 1 - 2x - 7
omeli [17]

Answer:

x = 0

Step-by-step explanation:

2x−6=3x+1−2x−7

Step 1: Simplify both sides of the equation.

2x−6=3x+1−2x−7

2x+−6=3x+1+−2x+−7

2x−6=(3x+−2x)+(1+−7)(Here we Combine Like Terms)

2x−6=x+−6

2x−6=x−6

Step 2: Subtract x from both sides.

2x−6−x=x−6−x

x−6=−6

Step 3: Add 6 to both sides.

x−6+6=−6+6

x=0
