Question

Find three different solutions of the each of the following equations.
ii) 2x - y=7
y = 6x
v) 10x + Ily=21
vi) x+y=0
v) 13x - 12y - 25​

Answer 1

Step-by-step explanation:

If y=1 put in equation we get

13x−12×1=25

⇒13x−12=25

⇒13x=25+12=37

⇒x=

(ii)13x−12y=25

If y=2 put in equation we get

13x−12×2=25

⇒13x−24=25

⇒13x=25+24=49

⇒x=

If y=3 put in equation we get

13x−12×3=25

⇒13x−36=25

⇒13x=25+36=61

⇒x=
