Question

5y+10=4y–10,Solve the given equation without transposing and check your result.

Answer 1

Answer : y = -20

5y+10=4y–10 where "y" = -20

Explanation :-

Given :

5y+10=4y–10,Solve the given equation without transposing and check your result.

5y+10=4y–10

Subtract 4y on both sides

5y - 4y + 10 = 4y - 4y - 10

y + 10 = - 10

Subtract 10 on both sides

y + 10 - 10 = - 10 - 10

y = - 20.

Checking results :-

Substitute the value of Y :-

5y+10=4y–10

5(-20) +10 = 4(-20) -10

-100 + 10 = -80 -10

-90 = -90

LHS = RHS

Hence, verified.

Answer 2

Answer-: -20
Solution-:1)5y+10=4y+10
2)5y+4y-10=4y-4y-10
(substracting 4y both the sides)
3)y+10=-10
4)y+10-10=-10-10
(substracting 10 both the sides)
5)y=-20
