Question

express the equations 2x+3y-4=0 and 3x-y+5=0 by graphical method

Answer 1

Step-by-step explanation:

2x+3y-4=0 - eq 1

2x+3y=4

3x-y=5 - eq 2

from eq 2

3x=5+y

x=5+y/3

substitute in eq 1

2(5+y/3)+3y=4

10+2y/3+3y=4

10+2y+9y/3=4

10+11y/3=4

10+11y=12

11y=2

y=2/11

from 1

2x+3 (2/11)=4

2x+6/11=4

22x+6/11=4

22x+6=44

22x=38

x=19/11
