Question

Find the four different solutions of each of the following equations
i) x + 2y = 3
( ii) 2x + 3y = 4
fii) 2(x - 1) + 3y = 4.​

Answer 1

Answer:

1- x=1 then y= 1

2- x=1 then y = 2/3

iii- x=2 then y= 2/3

Step-by-step explanation:

i - put 1 in in x then

1+2y=3

put one into another side

2y =3-1

2y=2

y=2/2

y=1.

ii - puting 1 in x we got

2×1+3y= 4

2+3y =4

3y= 4-2=2

y=2/3.

iii - putiing the value of x as 2

2(2-1) +3y= 4

2(1)+3y =4

2+3y =4

3y= 4-2

y= 2/3.

Answer 2

Answer:

I) X + 2y = 3

→ X= -1, 7, -3, 9 Y= 2, -2, 3, -3

II) X= 5, -1, 2, -4 ; Y = -3, 2, 0, 4
