Answer:
20)x=-1/2
21)x=10
Step-by-step explanation:
20)6x-2/5=2x-2/3-1/3
6x-2/5=2x-2/3
3(6x-2)=5(2x-2)
18x-6=10x-10
8x=-4
x=-4/8
x=-1/2
Substiting the value x=-1/2 in
the equation
(6×-1/2)-2/5=(2×-1/2)-2/3
(-3-2)/5=(-1-2)/5
-5/5=-3/3
-1=-1
LHS=RHS
21)(z-1)/3=(z-2)/4 +1
(z-1)/3=(z-2+4)/4
(z-1)/3=(z+2)/4
4(z-1)=3(z+2)
4z-4=3z+6
4z-3z=6+4
z=10
Substiting the value z=10 in the equation
(10-1)/3=1+(10-2)/4
9/3=1+8/4
9/3=1+2
3=3
LHS=RHS
