Question

solve the following equation and check your answers
​

Answer 1

Step-by-step explanation:

6x-2/5 =2x-1-1/3

6x-2/5= 2x-2/3

cross mutipling,

18x-6=10x-10

18x-10x=-10+6

8x=-4

x=-4÷8

x=-1/2

Answer 2

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
