Question

multiply (3/5x + 1/2y) by (5/6+4y)​

Answer 1

Answer:

Given:

3x

1

−

4y

1

+1=0;

5x

1

+

2y

1

=

15

4

Assuming,

x

1

=X,

y

1

=Y, we get

from the first equation

3

X

−

4

Y

+1=0

⇒4X−3Y+12=0 ...(1)

from the second equation

5

X

+

2

Y

=

15

4

multiply by 30 on both sides we get

⇒6X+15Y=8 ...(2)

Now, Multiplying (1) by 5 and then add (2) to it, we get

26X+52=0

⇒X=−2

⇒

x

1

=−2⇒x=−
