8/[4(x-21)31] = 9/[4(y+6)]
32y + 192 = 1116x - 23436
5907 = 279x - 8y --->> simplest form

those are in actuality an identical undertaking. in the 1st, element out a three from the two numerator and denominator. 3x+6 = 3(x+2) 3x-6 = 3(x-2) Then the quotient = 3(x+2) / 3(x-2) = 3/3 * (x+2)/(x-2) = one million * (x+2)/(x-2) = (x+2)/(x-2) the 2nd works an identical way. you ought to settle on what extensive form to element out.

8/4(x-21)31=9/4(y+6)
8x-168/4=9y+54/4
Multiply both sides by 4
8x-168 = 9y+54 -------------(i)
8x=9y+54+168
8x=9y+222
x=9y+222/8 -------------(ii)
Put value of x in eq. 1
(i)=> 8x-168 = 9y+54
8x(9y+222/8)=9y+54
72y+222=9y+54
72y+222-54=9y
72y+168=9y
168=9y-72y
168= -63y
168/-63=y
