Question

PLS HELP
Find the sum.

Answer 1

The answer is 8b + 6x + 5c + 11.

Explanation:

Since 8b, 6x, and 5c are all different variables, we cannot add them. However, we can still add 7, -4, and 8.

Answer 2

Answer: 6x+8b+5c+11

Explanation:

`\left(8b+7\right)+\left(6x-4\right)+\left(5c+8\right)`

`=8b+7+6x-4+5c+8`

`\mathrm{Group\:like\:terms:}`

`=6x+8b+5c+7-4+8`

`\mathrm{Add\:the\:numbers:}\:7-4+8=11`

`=6x+8b+5c+11`
