1500 total surveys sent
Returned: 245 + 173 + 185 + 92 = 695
1500-695 = 805
You reduce it to 1/6 because 6 goes into 6 once and 6 goes into 36 six times giving you 1/6
Okay, so since both y values share the same number, let's add both equations so the y values cancel out leaving us to solve for x.
10x+(-5x)=5x
7y+(-7y)=0
1+24=25
Now we have 5x=25
divide both sides by 5 and we have x=5
Now that we know x=5, we can plug it into one of the problems to find y.
Let's do 10(5) +7y=1
50+7y=1 subtract 5 and we get 7y=-49
divide -7 from both sides and we get y=-7
so there you have it x=5 and y=-7
