Twice a number added to half of equals 20 find the number
Let assume number = x
2x + x/2 = 20
4x + x = 40
5x = 40
X = 8
2x + x/2 = 20
4x + x = 40
5x = 40
X = 8
2x+x/2=20
3x/2=20
3x=20×2
3x=40
X=40/3
3x/2=20
3x=20×2
3x=40
X=40/3

let the number we dont know = x
2x+x/2=20
now multply 2 from both sides
2(2x)+x=2(20)
4x+x=40
now add 4x to x
5x=40
now divide both sides from 5 to eliminate coifficient
5x/5=40/5
now we get 8 as an answer
x+8

plsssssssssss
2x+x/2=20
now multply 2 from both sides
2(2x)+x=2(20)
4x+x=40
now add 4x to x
5x=40
now divide both sides from 5 to eliminate coifficient
5x/5=40/5
