Question 20995
Let x = the number


Just translate the sentence into an equation:
{{{10+ (x-6)/4= 30 }}}


Let's begin by subtracting 10 from each side:
{{{(x-6)/4=20}}}


Multiply both sides by 4:
{{{x-6 = 80}}}
{{{x=86}}}


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!
