2x-3=15

1 answer

To solve for x in the equation 2x - 3 = 15, you need to isolate x on one side of the equation by performing inverse operations.

First, add 3 to both sides:

2x - 3 + 3 = 15 + 3

2x = 18

Next, divide both sides by 2:

2x/2 = 18/2

x = 9

Therefore, the solution to the equation 2x - 3 = 15 is x = 9.
