Answer 2

Answer:

Step-by-step explanation:

0.3(8+y) =0.8(4y)

above is our initial Question.

Since the decimals are very painful to handle, let's reduce it into a simpler problem.

0.8 can be written as 8/10

similarly, 0.3 can be written as 3/10

now our new equation is

8(8+y)/10 = 3(4y)/10

now we can simply cancel 10 on both sides.

thus our equation now becomes

8(8+y) = 3(4y)

now open the brackets

64 + 8y = 12y

transposing 8y to RHS

64 = 12y -8y

4y = 64

y = 16

EDIT: oh, as for verification

just substitute the value of y we obtained in the reduced equation

8(8 + y) = 3(4y)

8(8 + 16) = 3(4×16)

8×24 = 3×64

192 = 192

since LHS = RHS

hence proved.

Hope this helps ☺️
