Answer:
The given equation is 2x + y = 3⇒y = 3 - 2x ... 1Put x = 0 in 1, we get y = 3So, 0,3 is a solution. Put x = 1 in 1, we get y = 1So, 1,1 is a solution. Put x = 2 in 1, we get y = -1So, 2,-1 is a solution.
Step-by-step explanation:
2x + y = 3
Keeping y = 0, 1 and x = 0
2x + (0) = 3
x = 1.5
\textsf{\red{ Coordinates : ( 1.5, 0 ) }} Coordinates : ( 1.5, 0 )
2x + (1) = 3
2x = 3 - 1
x = 1
\textsf{\red{ Coordinates : ( 1, 1 ) }} Coordinates : ( 1, 1 )
2(0) + y = 3
y = 3
\textsf{\red{ Coordinates : ( 0, 3 ) }} Coordinates : ( 0, 3 )
