8x plus 14 equals -10 what is x?

Answer 1

Though i passed my GCSE Maths in 2008, i think i know the answer. See my method below:

8x+ 14= -10

Add 10 to both sides to get rid of the -10. This leaves you with;

8x+ 28= 0

You can guess that x needs to be a negative number that you can multiply by 8 to get -28.

7x8= 28, so -7x8=-28

Therefore;

x=-7

Interesting but unfortunately wrong, 8x-7 =-56 (maybe I'm wrong though I did my A-levels over 20 years ago)

8x + 14 = -10

8x = -10 - 14

8x = -24

x = -24/8

x = -3
