Question

Solve by substitution method 2x+3y-9=0 , 3x+2y-11=0.

Answer 1

Answer:

X=5, Y= -1/3

Step-by-step explanation:

3x+2y= 11. --i

2x+3y= 9. --ii

3y=9-2x

y= (9-2x)/3

putting the value of y in equation i

3x+2(9-2x)/3 =11

3x+(8-4x)/3= 11

9x+8-4x=33

9x-4x= 33-8

5x=25

x= 5

putting the value of x in equation ii

2*5+3y=9

10+3y=9

3y= 9-10

y=-1/3
