Question

2x _ y = 7 find the three different solutions of the following equation of 2 x minus y equal to 7

Answer 1

☺️hey mate! here's your answer!☺️

equation :-

2x - y = 7
--------------
if ,

x = 0

2 (0) - y = 7

=> 0 -y =7

=> y = -7
--------------------
and if,

y = 0

2x - 0 = 7

=> 2x = 7

=> x = 7/2
--------------------
and ,

let x = 1

so,

2(1) - y = 7

=> 2 - y = 7

=> -y = 7 -2

=> -y = 5

=> y = -5
----------------------------
thus, three different solutions for this equation are :-

when,

(1) x = 0 , y = -7

(2) x = 7/2, y = 0

(3) x = 1 , y = -5

hope you understood!
