We are given with two equations 2x − 3y = −1 and <span>11x − 9y = −13. The problem says that when the first equation is multiplied by -3 which results to -6x + 9y = 3, the sum of the resulting equation and the second one is equal to 5x = -10. We verify this: -6x + 11x = 5x while -9 y and 9 y cancels out. 3+-13 equals -10. Hence the total is really 5x = - 10.</span>
Answer:
13x
Step-by-step explanation:
Well if her simplifies 1 3/7 to 1 1/2 and 5 4/5 to 6 then he would be overestimating because 1 1/2 is greater than 1 3/7 and 6 is greater than 5 4/5
Hope this helps!

p =
Step-by-step explanation:
q=
- r÷ t using BODMAS
q =
- (r/t)
q + r/t = 
p=
It will cost 6.50$ because you divide 15.60/12 to find how much one pound is and then multiply by five to get $6.50
