Question

17. Find four solutions of linear equation x + 2y = 3​

Answer 1

Answer:

x+2y=3

y = x-3

x+2y=3 can be written as x + 2(x-3)

x+2(x-3)=3

x+2x-6=3

3x=9

x=9/3=3

y=3-3=0

Therefore x=3 and y=0

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Given:-

the linear equation x+2y=3

To find:-

Find four solutions of x+2y=3

Solution:-

Given equation is x +2y=3----------(1)

1)Put x=0 then (1) becomes

=>0+2y=3

=>2y=3

=>y=3/2

The solution is (0,3/2)

2) Put y=0 then (1) becomes

=>x+2(0)=3

=>x+0=3

=>x=3

The Solution is (3,0)

3) Put x=1 then (1) becomes

=>1+2y=3

=>2y=3-1

=>2y=2

=>y=2/2

=>y=1

The solution is (1,1)

4) Put y=-1 then (1) becomes

=>x+2(-1)=3

=>x-2=3

= x=3+2

=>x=5

The solution is (5,-1)

Answer:-

The four solutions are (0,3/2);(3,0);(1,1);(5,-1)
