because since all abc and xy have the same coefficients it makes it easier.
i just made a=-2, b=-4,and c=4 because when added up it equals -2
i also made both x and y =5 becasue when added up it equals 10
so, -9(-2)+2(5)-9(-4)-9(4)+2(5)
18+10+36-36+10=38
Final result :

Equation at the end of step 1 :
1
— • (27y - 51z - 6)
3
Step 2 :
Pulling out like terms :
3.1 Pull out like factors :
27y - 51z - 6 = 3 • (9y - 17z - 2)
Final result :
9y - 17z - 2
1985year ->275cell phones->100%
1994year -> x cell phones ->100%+360%
40% • (1994-1985)= 40% • 9= 360%
275 cell phone 100%
X cell phones. 100+360%=460%
x=275•460%/100%
x=12420/100
x=1265
99% sure this is a correct answer
x=275 • 460%/100%
x=12,420/100
x=1265
1994-1985= 9 yrs • 40%= 360%
