I need help and steps of how u got it

Mathematics
1 answer:
Gnom [1K]3 years ago
3 0

Answer:

A)  4

Step-by-step explanation:

There are a couple of ways to get this but this is how I did it:

1.  Multiply the second equation by 1/4 to get the same fraction for y as the one in the first equation

1/4 x + 1/8 y = 2

1/4 (1/3 x + 1/2 y = 4)

1/12 x + 1/8 y = 1

2.  Subtract the first equation from the new equation

    1/12 x + 1/8 y = 1

<u>    - 1/4 x - 1/8 y = -2</u>

-1/6 x= -1

3.  Divide both sides by -1/6

  <u>-1/6</u> x= <u>-1</u>

   -1/6    -1/6

     x = 6

4. Substitute 4 in for x in the original equation:

1/4 (6) + 1/8y = 2

6/4 + 1/8y = 2

1/8y = 1/2

  y = 4
