Nope.
5x+1=15-2x
7x=14
x=2

5x + 1 = 15 - 2x
5x + 1 + 2x = 15 - 2x + 2x
7x + 1= 15
7x + 1 - 1 = 15 - 1
7x = 14
7x / 7 = 14 / 7
x = 14/7
x = 2
- - - - - - - - - - s-

5X+1=15-2X
=> 5X+2X=14
=> 7X= 14
=> X=2[ans.]

Keep x one side and numbers one side
If + comes crosses = it will become -
so
5x+2x=15-1
7x=14
x=14/7
x=2

5x+1=15-2x
5x+2x+1=15-2x+2x
7x+1=15
7x+1-1=15-1
7x=14
7/7x=14/7
x=2
Check:
5(2)+1=15-2(2)
10+1=15-4
11=11

5x+1=15-2x
+2x +2x get the x on the same side
---------------------
7x+1=15
-1 -1 get the num. on the same side
---------------------
7x=14
------------- divide 7 on each side
7 7
x=2
