Question

Examine -2 is the solution of 2x+4=5

Answer 1

YOUR ANSWER
>>>>>>>>>>>>>>>>>>>>>>

TO EXAMINE -2 IS THE SOLUTION,

PUT THE VALUE OF x AS -2

2 × (-2) + 4 = 5
-4 + 4 = 5
0 = 5

SINCE LHS (0) IS NOT EQUAL TO RHS (5),
WE CAN SAFELY CONCLUDE THAT -2 IS NOT A SOLUTION OF EQUATION 2x + 4 = 5

Answer 2

hello friend,

To examine -2 as the solution of 2x+4=5 put value of x as -2.
To be the solution of given solution RHS should be equal to LHS.
RHS is 5
LHS
2×(-2)+4
-4+4
=0
Here we can see that RHS is not equal to LHS.
hence -2 is not the solution of 2x+4=5.

hope its correct.
