Question

Stories the sum of X and 12 is greater than or equal to 8 please help me I've been stuck on this question for 2 and 30hours and I'm really horrible at now

Answer 1

Here’s a short explanation and some work shown! hope it helps

Answer 2

your inequality would look like

`x + 12 \geqslant 8`
to solve, you need to subtract 12 from both expressions leaving x isolated on the left and -4 on the right

`x \geqslant - 4`
what this means is your solution for x is any number that is -4 or greater.


`- 4 + 12 \geqslant 8 \\ 8 \geqslant 8`

`0 + 12 \geqslant 8 \\ 12 \geqslant 8`



if you put a value in for x that is lower that -4, the inequality will not be true.

`- 5 + 12 \geqslant 8 \\ 7 \geqslant 8`
since 7 is not greater than or equal to 8, the value of -5 is not a solution for x in the inequality
