Question

answer answer answer answer​

Answer 1

a) 5y+6=16
5y=16-6
5y=10
y=10/5
y=2 (iii)

b)3(y-3)=0
3y-9=0
3y=0+9
3y=9
y=9/3
y=3 (vi)

c)3=y/2
3*2=y
y=6 (i)

d)y/6-2=1
y/6=1+2
y/6=3
y=3*6
y=18 (v)

e)y-1/3=2/3
y=2/3+1/3
y=1/1
y=1 (iv)

f)4(3-y)=-20
12-4y=-20
-4y=-20-12
-4y=-32
4y=32 [minus gets canceled on both the sides]
y=32/4
y=8 (ii)
