Question

x=2,y=3 is a solution of a pair of linear equation ________

a.2x+3y-13=0
b.2x-3y+13=0
c.3x+2y-31=0
d.2x+3y+13=0​

Answer 1

$\huge \mid{ \underline{ \overline{ \underline{\overline \pink{\bold{ \: \: Aɴsᴡᴇʀ \: \: } }}} }}\mid$

a) 2x + 3y - 13 = 0

=> 2 × 2 + 3 × 3 - 13 = 0

=> 4 + 9 - 13 = 0

=> 13 - 13 = 0

=> 0 = 0

so, x = 2 , y = 3 is a solution of a pair of Linear equation

• 2x + 3y - 13 = 0

Answer 2

Answer:

optikn a is right

by putting x=2 and y=3 in (a) option

2(2)+3(3)-13

4+9-13

13-13=0
