Question

solve this simultaneous equation using substitution method plz 2x+3y=3 6x-12y=-5​

Answer 1

Answer:

2x+3y=3------eq i

x= 3-3y/2------eq ii

6x-12y=-5-----eq iii

put the value of x from eq i in eq iii

6(3-3y)/2-12y=-5

3(3-3y)-12y=-5

9-9y-12y=-5

-21y= -5-9

-21y= -14

y= -14/-21

y= 2/3

put the value of y in eq ii

x= 3-3×2/3

______ = 3-2/2

2

x= 1/2
