Answer: 
Explanation:
Follow PEMDAS in reverse to undo what's happening to x.
We first add 1 to both sides, then divide both sides by 5 to fully isolate x.
Refer to the steps below to see what I mean.

The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.
The solution set for x is anything -3 or larger.
If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}
I’m not too sure if I did it correct, but the answer I got was -6x^2+36. I just assumed you’d solve it as usual and then multiply (-3) after distributing-2 to x^2-6. Hope this helps.
X = 42 - 19, so A - x = 23
Halving-reduce by half or think what is fifty% of the number or divide by two
doubling-add the number you got to the same number or multiply by two
Halving Ex.:6/2=3
Doubling ex.: 9+9=18 or 6*2=12
THE ANSWER IS 42 I THINK THAT HE DONE IT 42 TIMES AND THAT IS SO GOOD HE HAD 42 MIN ON THE CLOCK HE DONE PRETTY GOOD YOU ARE AT LEAST TO DO IT 3 TIMES A DAY MORNING ,AFTERNOON AND THE EVENING THAT IS PRETTY DANG GOOD
