Answer:
7. y+5/3y-2 = -5/2
= 2(y+5)= -5(3y-2)
=2y+10=-15y+10
=2y+15y=10-10
=17y=0
=y=0
-------------
8. 42-x/2= x+2
=84-x=2(x+2)
=84-x=2x+4
= -x-2x= 4-84
= 3x= 80
=x= 80/3
=x=26.666
-----------------
9. 16/5-x=2x-5
= 16-5x=5(2x-5)
= 16-5x= 10x - 25
=-5x-10x=-25-16
=-15x=-41
=x=41/15
=x=2.73
--------------------
10. 5/3-x/3=2x/3-7/3
= 3(5-x)= 3(2x-7)
=15-3x= 6x-21
= -3x-6x= -21-15
= -9x= -36
=x= 4
