Given equations A and B as 2/5x+y=12 and 5/2y-x=6 respectively which expression will eliminate the variable X a) 5/2A+2/5B b)5/2
frutty [35]

Answer:

C) A+\frac{2}{5}B

Step-by-step explanation:

Given Equations:

A) \frac{2}{5}x+y=12

B) \frac{5}{2}y-x=6

In order to eliminate x we need to multiply \frac{2}{5} to equation B and add it to A.

Multiplying \frac{2}{5} to B.

⇒ \frac{2}{5}\times (\frac{5}{2}y-x)=\frac{2}{5}\times 6

⇒ (\frac{2}{5}\times\frac{5}{2}y)-(\frac{2}{5}x)=\frac{12}{5}

⇒ y-\frac{2}{5}x=\frac{12}{5}

Adding it equation A.

   \frac{2}{5}x+y=12

+ -\frac{2}{5}x+y=\frac{12}{5}

We get 2y=\frac{72}{5}

Thus x is eliminated.

So, the expression used to eliminate x is:

A+\frac{2}{5}B

You get a common denominator. It's 36. Then multiply accordingly to get 16/36-3/36 = 13/36. Hope this helps.
