Question

3 X + 4 Y =10 ;4x +y=9...solve this by elimination method ....my answer not correct​ly coming

Answer 1

Answer:

3 X + 4 Y =10---------------------(1)

4x +y=9. -------------------(2)

equation 2multiply by 4

16x+4y=36--------------------(3)

equation (1)and(3) substrate

3 X + 4 Y =10

-16x + -4y =- 36

-13x=-26

x=-26/-13

x=2

x=2 put in equation (1)

3 X + 4 Y =10

3(2)+4y=10

6+4y=10

4y=10-6

y=4/4

y=1

(x,y)=2,1
