Okay first
22x+11=5x-7
You need to move the variables so it eaquals 0
22x+11-5x+7=0
Now combine like terms
17x+18=0
Move 18 over to divide
17x=-18
X= -1.1 or just -1
Good luck! :D

the plant in front of the house, grew 3.75 inches each week for 4 weeks. and the plant in the back of the house, grew 4 inches each week for 5 weeks. but since the plant in the back of the house was 5 weeks and the one in the front had 4 weeks. you would calculate each plant for the same amount of weeks. so if you would have done 20/4 and 15/4 or 20/5 and 15/5, the plant in the back would have grown fatser then the one in the front.
work:
15/4=3.75
20/5=4
20/4= 5
15/5= 5
