Question

state whether 4, - 5 is solution of X + 2 Y equal to 3 or not

Answer 1

According to the statement,

4 + 2(-5) = 3
4 + (-10) = 3
4 - 10 = 3
-6 not equal to 3

Hence, this statement is false...

Answer 2

heya...

here is your answer...

Let us take x=4 and y=-5

x+2y=3

substitute the values of x and y in the equation.

4+2(-5)=3

4+(-10)=3

4-10=3

-6 is not equal to 3.

so 4,-5 is not a solution.
