Question

x+6y=10,2x-3y=8 by substitution method​

Answer 1

Answer:

Given, x+6y=10______(i)

2x-3y=8_______(ii)

(I) =x=10-6y_____(iii)

substituting the value of x=10-6y in (ii) we get,

2(10-6y) -3y=8

=20-12y-3y=8

=-15y=8-20

=y=-12/-15

=y=4/5

(iii) =x=10-6*4/5

=x=10-24/5

=x=50-24/5

=x=26/5

Answer 2

Answer:

x = 26/5

y = 3/5

Step-by-step explanation:

x + 6y =10

(2x -3y =16)*2

and add above 2 equations
