Question

If -4x + 5y is added to 3x + 2y then the answer will be

a) 3x + 6y b) 2x + 5y c) x - 3y d) -x + 7y

Answer 1

Answer:

Option D) -x + 7y is correct

Step-by-step explanation:

• -4x + 5y

• 3x + 2y

→ -4x + 5y + (3x + 2y)

→ -4x + 5y + 3x + 2y

→ -4x + 3x + 5y + 2y

→ -x + 7y

Hence, among the given options, option D) -x + 7y is correct.

Answer 2

$\huge{\boxed {\tt{Solution :}}}$

Given:

• If -4x + 5y is added to 3x + 2y then answer will be :

(a) 3x + 6y □ (b) 2x + 5y □ (c) x - 3y □ (d) -x + 7y □

To Find :

• The answer.

Now we head to the solution :

$\sf{: \implies( - 4x + 5y) + (3x + 2y)} \\ \\ \sf{: \implies - 4x + 5y + 3x + 2y } \\ \\ : \implies { \boxed{ \tt{- x + 7y }}}$

$\bf {\therefore{The\:answer\:will\:be\: (d)\:-x+7y.}}$
