Let x = the number
Just translate the sentence into an equation:
Let's begin by subtracting 10 from each side:
Multiply both sides by 4:
Check: Do what the sentence says to do!
Begin with x = the number = 86
Six is subtracted from a number: 86-6=80
Result is divided by four: 80/4= 20
This result is added to 10: 20 + 10 = 30
It checks!
