2x+12=18−x
Add x to both sides.
2x+12+x=18
Combine 2x and x to get 3x.
3x+12=18
Subtract 12 from both sides.
3x=18−12
Subtract 12 from 18 to get 6.
3x=6
Divide both sides by 3.
x= 6/3
Divide 6 by 3 to get 2.
x=2
Add x to both sides.
2x+12+x=18
Combine 2x and x to get 3x.
3x+12=18
Subtract 12 from both sides.
3x=18−12
Subtract 12 from 18 to get 6.
3x=6
Divide both sides by 3.
x= 6/3
Divide 6 by 3 to get 2.
x=2
streamlined solution
2x+12=18−x
2x + x = 18-12
3x = 6
x = 2
That's all you would have to show in your solution.
2x+12=18−x
2x + x = 18-12
3x = 6
x = 2
That's all you would have to show in your solution.
Just so you know the final answer is x = 2...
Hope this helps!!
