Question

Fimd the linear equation with the help of cross multiple method of x+y=7and 2x-3y=11

Answer 1

Answer:

X= 6.2 y= .8 it is a right answer

Answer 2

Answer:

X+y=7................1

2x+3y=11...............2

Step-by-step explanation:

X Y 1

1 -7 1 1

3 -11 2 3

= X/(1)(-17)-(3)(-7) = y/(-7)(2)-(-17)(1) = 1/(1)(3)-(2)(1)

= X/(-17)-(-21) = y/(-14)-(-17) = 1/(3)-(2)

= X/-17+21 = Y/-14+17 = 1/3-2

= X/4 = Y/3 = 1/1

=X/4 = 1/1

X=4

=Y/3 = 1/1

Y =3
