2x - 4 = 7 + x
Transpose x
2x - 4 - x = 7 + x - x
x - 4 = 7
Transpose 4
x = 4 + 4 = 7 + 4
x = 11

Check
2x - 4 = 7 + x
2(11) - 4 = 7 + 11
22 - 4 = 18
18 = 18

2x -4 = 7 + x ( Put variable x and constants together)
2x - x = 7 + 4 (Simplify)
x = 11
Verification
x = 11 => 2(11) - 4 = 7 + 11
22 - 4 = 18
18 = 18

2x-4=7+x
Add 4 to both sides
2x = 11 + x
Subtract x from both sides
x = 11

Hey there!
Here's the answer.
2x-4=7+x --> Write the problem.
x-4=7 --> Subtract x on both sides of the equation.
x=11 Add 4 on both sides of the equation.
So the answer is x=11.
Hope it helps!
