X-5y=21 and-6x=24 solve by substitution
Zepler [3.9K]

Answer:

The value of x is (-4) and y is (-5)

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • x – 5y = 21
  • -6x = 24
<h3><u>To Find</u>;</h3>
  • Value of x
  • Value of y

Now,

-6x = 24

-6x/(-6) = 24/(-6)

x = -4

So, Substitute the value of x in x – 5y = 21

x – 5y = 21

-4 – 5y = 21

-4 + 4 – 5y = 21 + 4

-5y = 25/

-5y/(-5) = 25/(-5)

y = -5

Thus, The value of x is (-4) and y is (-5)

<h3><u>For </u><u>Verification</u>;</h3>

x – 5y = 21

-4 – 5(-5) = 21

-4 + 25 = 21

21 = 21

-6x = 24

-6(-4) = 24

24 = 24

L.H.S = R.H.S

Hence Verified!

Write the first three terms of the sequence defined by the recursive formula if a1=2.
gogolik [260]

The first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2

Given:

an =  \frac{an - 1}{4}  - 2

where,

n = number of terms

First term, a1 = 2

Second term, a2

an =  \frac{an - 1}{4}  - 2

a2 = {(2 - 1)/ 4} - 2

= 1/4 - 2

= (1-8) / 4

= - 7/4

Third term, a3

= {(3-1) / 4} - 2

= 2/4 - 2

= 1/2 - 2

= (1-4) / 2

= -3/2

Therefore, the first three terms of the sequence defined by the recursive formula are 2, -7/2 and -3/2
