Tania bought 4 more pounds of pears than wilma. together, tania and wilma bought 18 pounds of pears.
how many pounds of pears did wilma buy? need

The equation would be (x+4)+x=18. X stands for the amount of pears Wilma bought, and (x+4) is the amount of pears Tania bought (because she bought four more pounds than Wilma). (X+4)+x=18 2x+4=18 (now you subtract four from both sides) 2x=14 (to get x by itself, divide both sides by 2) X=7 Wilma bought 7 pounds of pears :3

Number of pears Tania bought - t
Number of pears Wilma bought - w

t = w + 4
t + w = 18

(w + 4) + w = 18
2w + 4 = 18
2w = 14
w = 7

Wilma bought 7 pounds of pears.

t = (7) + 4
t = 11

Tania bought 11 pounds of pears.
