The sum of two numbers is twenty-five Twelve less than four times one of the numbers is sixteen more than twice the other number?
Let's label one of the numbers with x, and the other number with y. So,
x + y = 25
4x - 12 = 2y + 16 add 12 and subtract 2y to both sides of the second equation; x + y = 25
4x - 2y = 16 +12 multiply by -4 the first equation; -4x - 4y = -100
4x - 2y = 16 +12 add both equations in order to eleminate x; 0 - 6y = -72 multiply by -1 to both sides;
6y = 72 divide by 6 both sides;
y = 12 Substitute 12 for y into the first equation;
x + y = 25
x + 12 = 25 subtract 12 to both sides;
x = 13
Thus, the numbers are 13 and 12. Check:
13 + 12 = 25
4(13) -12 = 2(12) +16 ?
52 -12 = 24 + 16 ?

Is it true hexadecimal numbers operate on a base- 10 number system?
It is only true in the sense that any numeric base, expressed in that base, is represented with the symbol "10". Confusing? Let's clarify that. Hexadecimal numbers use sixteen as the base. But how do you express the value sixteen in hexadecimal? Quite easy, it would be written as "10". The same is true in any other base. For example, in binary (base two), the value two is expressed as "10". In octal (base eight), the value eight is expressed as "10". In decimal (our familiar base ten), the value ten is expressed as "10". No matter what base you work in, the base itself will always be expressed as "10". That however is not the same thing as saying that hexadecimal numbers are based on the number ten. That is incorrect. Hexadecimal numbers use the base sixteen.
