x - 5 = 7
Step 3: Isolate the Variable
To solve for x, eliminate the constant term on the left. Add 5 to both sides of the equation:
x - 5 + 5 = 7 + 5
x = 12
Step 4: Check the Solution
Plug x = 12 back into the original equation to verify:
3(12) - 2(12) - 5 = 7
36 - 24 - 5 = 7
7 = 7 ✅
The solution checks and confirms x = 12 is correct.
