Answer:
x=3
Step-by-step explanation:
lets take x as the number
so
6(x-3)=x-3
since it says "6 times" we know that we will have to multiply the difference by 6 and it says the difference of a number and 3 is equal to 3 less than the number so we know that we are subtracting 3 from x
6x-18=x-3
6x-x=18-3
5x=15
x=3
X(x+5)=234
x^2 +5x=234
x^2+5x-234=0
Factor:
x^2+5x-234
(x-13)(x+18)
the integers are 13 and 18.
