So to better understand this question, let us define rational and irrational numbers first. Rational numbers are those numbers that can be written in fractions. On the other hand, irrational numbers are those numbers that cannot be written as fractions and the common example of it is pi. So, the rational number that is between 9.5 and 9.7 would be 9.6. This can be written as 9 and 3/5 or 48/5. And the irrational number would be <span>9.562359123571283578. Hope this answer helps.</span>

X +5+11x=12x+Y It says find the value of y that makes each equation true for all values of

sladkih [1.3K]

X + 5 + 11x = 12x + y

Simplify: 12x + 5 = 12x + y (We are adding x and 11x on the left side)

Subtract 12x from each side makes each zero.

5 = y

So we can plug in and test. I'm picking two random numbers to plug in for x. 10, and 82

x = 10, y = 5
10 + 5 + 11(10) = 12(10) + 5
125 = 125

x = 82, y = 5
82 + 5 + 11(82) = 12(82) + 5
989 = 989

So we verified y = 5

Here, I'll do the first one for you.
When they are talking about a number, use "x".
Since it says twice a number, you say 2x. Or 3x for three times the number
2x+12=3x-31
Then use algebra to find x. Get the numbers on one side and all the x's on the other.
2x+12+31=3x-31+31
2x+43-2x=3x-2x
x=43

Now do the rest on your own!
