24 -6x = 30 subtract 24 from both sides
-6x = 30 -24
-6x = 6 divide both sides by 6
-x =1
x = -1

24 = 30 + 6x
- 6 = 6x
x = - 1

+ 6x to both sides
24 = 30 + 6x
take 30 from both sides
-6 = 6x
divide by 6
x = -1

24 - 6x = 30
Transpose 24
24 - 6x - 24 = 30 - 24
- 6x = 6
Divide both sides of the equation by - 6
- 6x / - 6 = 6 / - 6
x = - 6/6
x = - 1

24-6x=30
-6x+24-24=30-24
-6x=6
x=-1
check: 24-6(-1)=24+6=30
