To solve the equation 3x + 5 = 2x + 7, we need to isolate the variable x.
Step 1: Start by getting all the terms involving x on one side and the constant terms on the other side. We can do this by subtracting 2x from both sides:
3x – 2x + 5 = 7
This simplifies to:
x + 5 = 7
Step 2: Next, we isolate x by subtracting 5 from both sides:
x = 7 – 5
This simplifies to:
x = 2
So, the solution to the equation 3x + 5 = 2x + 7 is x = 2.
