Question

Add 7x +14x, 4x-5x and -9x +4y give a solution​

Answer 1

Answer:

7x + 14x=21 x

4x-5x= -1x

-9x+4y= -9x +4y

21x + -(-1x) +(-9x) +4y

= 21x - 1x - 9x+4y

=11x + 4y (ANSWER)

Answer 2

Answer:

11x+4y

Step-by-step explanation:

let us first add all x-terms and then y-terms

i.e 7x+14x+4x-5x-9x=11x

as we have only 1 y-term i.e 4y

the answer will be 11x+4y.
