Step-by-step explanation:
2x-3y=7
when x=0
when x = 0
0-3y=7
= -7/3
when x=1
2-3y=7
-3y= 7-2
y= -5/3
when x=2
4-3y=7
-3y=7-4
y= -3/3
y= -1
when x=3
6-3y=7
-3y= 7-6

Step-by-step explanation:
Normal method
- 2x - 3x = 7
- = -1x = 7
- = x = 7/-1
Hit and trial method
- If x = 8, y = 3
- 2(8) - 3(3) = 7
- 16 - 9 = 7
- 7 = 7
Choosing method
- 2(20) - 3(11) = 7
- 40 - 33 = 7
- 7 = 7
