Question

solve linear equation by substitution method 2x+3y=17 , x+2y=10​

Answer 1

Answer:

x=4,y=3

Step-by-step explanation:

2x+3y=17. -(equation I)

x+2y=10. -(equation ii)

from equation (I)we get,

2x+3y=17

or, 2x=17-3y

or, x=17-3y/2. -(equation A)

putting the value of x in equation(ii)

x+2y=10

or, 17-3y/2+2y=10.

or,17-3y+4y/2=10

or,17+y/2=10

or,17+y=20

or,y=20-17

y=3

putting the value of y in equation A

x=17-3y/2

or,x=17-3×3/2

or,x=17-9/2

or,x=8/2

x=4

required answer:-x=4

y=3
