5x + 3x = 8x

8x + 2

FINAL ANSWER: 8x + 2

You would add 5x and 3x because they are like terms. The 2 is just a regular number, it doesn’t have a variable along with it.

5x + 2 + 3x

add same types of numbers

5x + 3x + 2

8x + 2

find x

8x + 2 = 0
8x + 2 (-2) = 0 (-2)
8x = -2
8x/8 = -2/8

x = -1/4

hope this helps
