Answer:
No solutions
Step-by-step explanation:
6x+2y=20
-3x-y=-4 (by rewriting)
So
6/-3 = 2/-1≠20/-4
-2=-2≠-5
So it has no solutions
3/12% = 25
<em>Therefore, 3 is 12% of 25.</em>
Answer: 10 × 3 + 4 + 5 × 2 + 1 + 3 × 100 = 345

is already in simplest form because 23 is a prime number, which means that it is only divisible by 1 and itself (23). Hope this helps! :)
