x+(x-31)+(x-22)= 61

Answer 1

x+(x-31)+(x-22)= 61

Expand this expression first

ie. x+ x -31 + x - 22 = 61

ie. 3x -31 -22 = 61

3x - 53 = 61
3x = 61 + 53

3x = 114

x = 114/ 3

x = 38

Done!

Answer 2

you combine all common factors so 3x-53=61. then add 53 to both sides to get 3x=114. then divide both sides by 3 to get x=38 :)
