6x - 7 = 4x + 11
6x = 4x + 11 + 7
6x - 4 x = 18
2x = 18
x = 18/2
x= 9.
therefore:
6(9) -7 = 4(9) + 11
54 - 7 = 36 + 11
47 = 47.

6X - 4X = 7 + 11 , 2X = 18 , X = 9, X = 3 squared

6x - 7 = 4x + 11 subtract 4x from each side
2x-7=11 add 7 to each side
2x=18 divide by 2
x=9

6x - 7 = 4x + 11
6x - 7 - 4x = 4x + 11 - 4x --> subtract 4x from both sides to get x on one side and the number on the other.
2x - 7 = 11
2x - 7 + 7 = 11 + 7 --> add 7 to both sides
2x = 18
2x/2 = 18/2 --> divide both sides by 2 to get x by itself.
x = 9
Hope this helps
