Question

Write three different solutions for the equation 4x-y=6

Answer 1

Answer:

Step-by-step explanation:

4x+y=9

If x=0 then

x×0+y=9

⇒y=9

(0,9)

(ii)4x+y=9

If y=0 then

4x+0=9

⇒4x=9

⇒x=  

4

(iii)4x+y=9

If x=1 then

4×1+y=9

⇒4+y=9

⇒y=9−4=5

(1,5)

(iv)4x+y=9

If y=1 then

4x+1=9

⇒4x=9−1=8

⇒x=2
