Question

3x-1/2x-3=3x+4/2x+3

Cross multiply

3x-1(2x+3)=2x-3(3x+4)

6x^2+9x-2x-3=6x^2+8x-9x-12

7x-3=-x-12

7x+x=-12+3

8x=-9

X=-9/8

why we dont cut 9x ? plese urgent

Answer 1

we don't cut 9 x because when 9x come before = (LHS) then -9x changed into + 9x so We can't cut it as the sign of both term i.e, +9x and +9x would be same.

Hope it will help u.
