Question

C. Find the solution of any one of the following pair of Linear Equations 
( i ) 4x + 3y = 17 and 5x – 2y = 4 ( By Elimination Method )

Answer 1

Step-by-step explanation:

4x+3y=17 __ i

5x-2y=4. __ ii

equation 1 multiply by 2

2(4x+3y=17)

8x+6y=34

equation 2 multiply by 3

3(5x-2y=4)

15x-6y=12

Now Add both

8x+6y=34

+ 15x-6y=12

---------------------

23x = 46

x = 46/26

x = 2

Answer 2

Step-by-step explanation:

• from eq i

4x+3y=17

4x = 17+3y÷4

putting the value of x an eq ii

5x-2y=4

( 17+3y÷4)+2y=4

(17+3y+8y)÷4=4

17+11y÷4=4

17+11y=16

11y= 16-17

11y=1

y=1÷11

0.09

4x+3y=17

4x-3×0.09=17

4x-0.27=17

4x=17+0.27

4x=17.27

x=17.27÷4

x=4.3175
