Question

7. Write two solutions of the form x = 0, y = a and x = b, y = 0 for each of the following equations: (i) 5x – 2y = 10 (ii) - 4x + 3y = 12 (iii) 2x + 3y = 24​

Answer 1

Answer:

(i) 5x−2y=10

ifx=0

5(0)−2(y)=10

⇒y=−5

ify=0

5(x)−2(0)=10

5x=10⇒x=2

∴ The two solutions are (0,−5) and (2,0)

(ii) −4x+3y=24

ifx=0

3y=12⇒y=4

ify=0

−4x=12⇒x=−3

∴ The two solution are (0,4) and (−3,0)

(iii) 2x+3y=24

ifx=0

3y=24⇒y=8

ify=0

2x=24⇒x=12

∴ The two solution are (0,8) and (12,0)
