Answer:
I hope this answer may help you
Step-by-step explanation:
Given, 3x+4y=6
If x=0,
3(0)+4y=6
0+4y=6
y=3/2
If x=1,
3(1)+4y=6
3+4y=6
4y=3
y=3/4
If x=2,
3(2)+4y=6
6+4y=6
y=0
Three solutions are (0,3/2) (1,3/4) (2,0)

Equation = 3x + 4y = 6
━━━━━━━━━━━━━━━
➝ Put y = 0
3x + 4 (0) = 6
3x = 6
x =
x = 2
⇒ ( 2, 0)
━━━━━━━━━━━━━━━
➝ Put y = 1
3x + 4(1) = 6
3x + 4 = 6
3x = 6 - 4
3x = 2
x =
⇒ ( , 1)
━━━━━━━━━━━━━━━
➝ Put y = 3
3x + 4(3) = 6
3x + 12 = 6
3x = 6 - 12
3x = - 6
x =
x = - 2
⇒ ( -2 , 3)
━━━━━━━━━━━━━━━
So, the solutions are ( 2, 0), ( , 1), ( -2 , 3)
━━━━━━━━━━━━━━━
