Question

Verify the following equation

i) X+4 =2X ; X=4

ii) Y-7= 3y+8 ; y=3​

Answer 1

Answer:

i) x = 4

verification:

x+4 = 2x

4+4 = 2×4

8 = 8

therefore, LHS = RHS

ii) y = 3

y - 7 = 3y + 8

3 - 7 = 3×3 + 8

*question is wrong

Answer 2

Answer:

x+4=2x

putting value of x =2 WE GET....

4+4=2×4

8=8(Hence proved)

2. y-7=3Y+8

putting value of y =3

3-7=3(3)+8

-4=17(Hence not proved)
