Answers:
2x - 6y = 8 -> x = 4 + 3y
-3x + 9y = 12 -> x = -4 + 3y
Answer:
X is 83
Step-by-step explanation:
Subtract 180 because thats what all of them eaqual and you subtract 97 from 180
<h2>727</h2>
Step-by-step explanation:
Let us denote the three digit number by
, where
is the hundreds digit,
is the tens digit and
is the ones digit.
Hundreds digit =
= Ones digit = 
Sum of digits = 
So, 
On exchanging tens and ones digit, value increases by 45. So
is 45 greater than
.



∴ Required number is 727
Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57

Answer:
The measure of the complement angle is 
Step-by-step explanation:
Let
x-----> the angle
we know that
The complement of an angle is equal to 
The supplement of an angle is equal to 
we have
The complement of an angle is one-sixth the measure of the supplement of the angle

solve for x
