Question

B) From the sum of 3x+y+11 and (-y-11), subtract 3x-2y-11.



answer in explanation please​

Answer 1

Answer :-

In this question, we first need to find the sum of ( 3x + y + 11 ) and ( - y - 11 ). After getting the sum, we need to subtract ( 3x - 2y - 11 ).

Sum of ( 3x + y + 11 ) and ( - y - 11 )

→ ( 3x + y + 11 ) + ( - y - 11 )

Opening the bracket -

→ 3x + y + 11 - y - 11

Arranging like terms :-

→ 3x + ( y - y ) + ( 11 - 11 )

Solving the expression -

→ 3x + 0 + 0

→ 3x

Subtracting ( 3x - 2y - 11 ) from 3x

→ 3x - ( 3x - 2y - 11 )

Opening the bracket :-

→ 3x - 3x + 2y + 11

Arranging like terms :-

→ ( 3x - 3x ) + 2y + 11

Solving the expression :-

→ 2y + 11

Answer 2

Answer:

2y + 11

Step-by-step explanation:

Sum of 3x+y+11 and (-y-11) = 3x + y + 11 + (-y - 11) = 3x + y + 11 - y - 11 = 3x

Subtraction of 3x-2y-11 from the sum of 3x+y+11 and (-y-11) = 3x - (3x - 2y - 11) = 3x - 3x + 2y + 11 = 2y + 11
