Question

which is the equation?

1. x+y
2. 4+4=8
3.4x+4=5
4. none of these ​

Answer 1

Answer:

$\huge{\underline{\mathtt{\red {A}\pink{N}\green{S}\blue{W}\purple {E}\orange{R}}}}$

OPTION NO. 3 (4x + 4 = 5)

$\large {\underline {\underline {\fbox{DEFINITION:}}}}$

=> An equation is a solution in which the left hand side (LHS) is equal to the right hand side (RHS). It has an equal ( = ) mark in between.

For example,

=> 12 + 5 = 15 + 2

=> 17 = 17

=> LHS = RHS

CONCLUSION:-

Option No. 2 could be the answer as well BUT we are asked for an algebraic equation that is the one which contains variables.
