Question

write four solution of 2x+y=7.​

Answer 1

Given -

$2x + y = 7$

To find -

Four solutions of the above linear equation.

Solution -

$2(2) + (3) = 7$

$4 + 3 = 7$

$7 = 7$

______________________________________

$2(4) + ( - 1) = 7$

$8 + ( - 1) = 7$

$7 = 7$

______________________________________

$2(1) + 5 = 7$

$2 + 5 = 7$

$7 = 7$

_______________________________________

$2(0) + 7 = 7$

$0 + 7 = 7$

$7 = 7$

_______________________________________

$\therefore$ (2,3) (4,-1) (1,5) (0,7)

Are the solutions of the equation

${2x} + {y} = {7}$
