Let’s solve the equation step by step.
We are given:
x + 4 = 2x + 3
Our goal is to find the value of
x that makes this equation true.

Step 1: Get all the x terms on one side
Right now, we have
x on the left and
2x on the right. Let’s move the smaller x term (which is just
x) to the right side by subtracting
x from both sides.
So:
x + 4 - x = 2x + 3 - x
Simplify both sides:
Left:
x - x + 4 = 0 + 4 = 4
Right:
2x - x + 3 = x + 3
Now the equation is:
4 = x + 3

Step 2: Get x alone
We want to isolate
x, so let’s get rid of the
+3 on the right side. We do that by subtracting
3 from both sides.
4 - 3 = x + 3 - 3
Simplify:
Left:
1
Right:
x + 0 = x
So:
1 = x
Or written normally:
x = 1

Step 3: Check your answer
Always check! Plug
x = 1 back into the original equation:
Original:
x + 4 = 2x + 3
Plug in 1:
Left:
1 + 4 = 5
Right:
2(1) + 3 = 2 + 3 = 5
Both sides equal
5 →
✔ Correct!
