Question 798192
"the difference between 4 times a number and 3 is 25"


translates to


{{{4x - 3 = 25}}}


where x is some unknown number



Let's solve for x



{{{4x-3=25}}} Start with the given equation.



{{{4x=25+3}}} Add {{{3}}} to both sides.



{{{4x=28}}} Combine like terms on the right side.



{{{x=(28)/(4)}}} Divide both sides by {{{4}}} to isolate {{{x}}}.



{{{x=7}}} Reduce.

Answer:


So the solution is {{{x=7}}} which means that the unknown number is 7.
