Now, According to the question,

Y= 4×X................equation I

Also,Y= X+6.................equation II

Finally, Equating both equations, we get

X+6= 4X

or, 6=3X

or, X=2

Now Y= 4×X

= 4×2

Are the expressions x + x + 1 + x + 2 + x + 1 + x and 5x + 4 equivalent? Why or why not?
egoroff_w [7]

Answer:

yes

they are equivalent because lets say the X = 3 then you would have to answer

3 + 3 + 1 + 3 + 2 + 3 + 1 + 3

and that would = 19

and then on the other equation

5 x 3 + 4 = 19

So the both equal the same.
