Does (-2x+y=6)+ (y-2x=4) have no solution?
Answers
does -2x+y=6 and y-2x=4 have a solution
look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values
there is no solution
these 2 lines are paralell
NO SOLUTION

Trey earns s dollars. Then he earns an additional $40. So far, he earns (s+40).
Then this amount is doubled: 2(s+40)
At the end, he has $234. So the equation is
2(s+40) = 234
2s + 80 = 234
2s = 154
s = 77
An arithmetic approach (solving using addition) could have the equation as
(s+40) + (s+40) = 234
s + 40 + s + 40 = 234
2s = 154
s = 77

To find the values of a and b we must find two integers with a sum of 10. The numbers multiplied must be 24. We can now conclude we're looking for the numbers 4 and 6.
b can therefore either be 4 or 6. The answers are 4 and 6.

The numbers in Julian's pattern are composite numbers are 10,24,and 38.
What is composite numbers?
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.
here, we have,
3,10,17,24,31,38
Now, we get,
because 10 divided by 2 equals 5 so it's composite
because 10 times 1 isn't the only way to get the number 10,
same thing for numbers 24 and 38, 24 divided by 2 equals 12, 24 divided by 3 equals 8,24 divided by 4 equals 6
so it's composite,
and 38 divided by 2 equals 19.
Hence, The numbers in Julian's pattern are composite numbers are 10,24,and 38.

Dividing 2 fractions is equal to multiplying the first fraction by the inverse of the second: Inverse of fraction a/b is b/a, so the inverse of 10/21 is 21/10.
So (4/7) / (10/21) = (4/7) * (21/10)
Now you multiply the numerators between each others to get one numerator, and same thing for the denominators
(4/7) * (21/10) = (4*21) / (7*10) = 84/70.
Now we need to simplify the fraction we got. Both 84 and 70 can be divided by 14, so 84/70 = (84/14) / (70/14) = 6/5.
So the (4/7) / (10/21) = 6/5
Hope this Helps! :)

If we add 6 to both sides we get:
X - 6 + 6 = -5 + 6
X = 1
1-6=-5
If you're doing it straight across this way, then when you subtract one from six, (since six is larger than one,) it will become a negative number.
Hope that helped!
