i think its x= 2
10x+2=7
then you have to get rid of the numbers by its self on the x's side so you would subtract 2 from 7 and get
10x=5
then you have to divide it
and it becomes x=2

10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
6-x+12 = 10x+7 6+12-7 = 10x+x 11 = 11x x = 1
The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
