Obviously the apple trees are $2 more than the lemon trees. That makes the lemon trees $7. Did that in my head. If you want to show the work: you 10l+7w=133 and 7l+10w=139. That gives you 10l=133-7w which reduces to l=(133-7w)/10 by substituting l in the second equation, you get 7*(133-7w)/10+10w=139.so you have 93.1-4.9w+10w=139 Which means 5.1w=49.5 so w=49.5/5.1=9
