To find the value of x in the equation 2x + 3 = 3x + 4, we need to isolate x on one side of the equation. Let’s go through the steps:
- Start with the original equation:
2x + 3 = 3x + 4
- Subtract 2x from both sides:
3 = 3x – 2x + 4
- Simplify the equation:
3 = x + 4
- Next, subtract 4 from both sides:
3 – 4 = x
- Simplifying that gives us:
-1 = x
Therefore, the value of x is -1.
To double-check our answer, we can substitute x back into the original equation:
-
Substitute -1 for x in the left side:
2(-1) + 3 = -2 + 3 = 1
-
Substitute -1 for x in the right side:
3(-1) + 4 = -3 + 4 = 1
Since both sides equal 1, our solution x = -1 is confirmed.
