Question 339341: Thirteen less than twice a number is seventeen more than half the number. What is the number? I know the answer is 20, but what are the steps to get there? Thanks. Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! 2x-13 = x/2 +17
add -x/2
2x-x/2-13=x/2-x/2+17
2x-x/2 -13=17
add 13
2x-x/2 -13+13 =17+13
3x/2 = 30
multiply by 2
3x=2*30
divide by 3
x= 60/3
x=20
