Question

if a= 16x+8 ÷4 and b=15x-10÷-5 then a-b =?​

Answer 1

Answer:

7x is the correct answer

Explanation:

a=16x+8/4

b=15x-10/-5

a-b=(16x+8/4)-(15x-10/-5)

=16x+8/4 - 15x-10/-5

=16x+8/4 -(-15x-10/5)

=16x+8/4 + 15x-10/5

=80x+40+60x-40/20

=140x/20

=7x

Answer 2

Answer: x

Given : a = 16x + 8 / 4 and b = 15x - 10 / -5

To Find : a - b

Explanation:

a = 16x + 8 / 4

b = 15x - 10 / -5

∴ a -  b = (16x + 8 / 4) - (15x - 10 / -5)

            = (16x + 2) - (15x - (-2))

            = (16x + 2) - (15x + 2)

            = (16x - 15x) + (2 - 2)

            = x

∴ a - b = x
