Question

3×-1/5 - x/7 =3 and check the answer​

Answer 1

Step-by-step explanation:

3x-1/5-x/7=3

LHS RHS

3x/1-x/7-1/5 3

(3x×7/1×7)-(x/7)-1/5 3

(20x/7)-(1/5) 3

20x/7=(3+1/5)

20x/7=(3×5/1×5)+(1/5)

20x/7=16/5(cross multiply)

100x=112

×=(1.12 ) / (1 12/100)

LHS=RHS

Hence verified

Answer 2

Answer:

-21-5x/7 = 3

-21-5x=3*7

-21-5x=21

-5x=21+21

-5x=42

x= -42/5
