Question

Find 4 values of the equation 3x+5y=15 .​

Answer 1

Answer:

Let x be 0

3×0+5y=15

0+5y=15

y=15/5

y=3

Let y be 0

3x+5×0=15

3x=15

x=15/3

x=5

Let x be 2

3×2+5y=15

6+5y=15

5y=15-6

y=9/5

y=1.8

Let x be 1

3×1+5y=15

3+5y=15

5y=15-3

y=12/5

y=2.4

Answer 2

ANsWeR :-

First :-

3x + 5y = 15

Let 2 be the value of x .

3(2) + 5y = 15

6 + 5y = 15

5y = 15 - 6

5y = 9

y = 9/5

y = 1.8 ....[1]

Let 3 be the value of x .

3(3) + 5y = 15

9 + 5y = 15

5y = 15 - 9

5y = 6

y = 6/5

y = 1.2 ....[2]

Let 4 be the value of x .

3(4) + 5y = 15

12 + 5y = 15

5y = 15 - 12

5y = 3

y = 3/5

y = 0.6 ....[3]

Let 5 be the value of x .

3(5) + 5y = 15

15 + 5y = 15

5y = 15 - 15

5y = 0

y = 0/5

y = 0 ....[4]

Now , according x and y coordinates , we will arrange the values :-

[1] = ( 2 , 1.8 )

[2] = ( 3 , 1.2 )

[3] = ( 4 , 0.6 )

[4] = ( 5 , 0 )
