Solve simultaneously:
<span>15x-8y=52 and
6x+14y=38
</span>
Let's solve this system thru elimination by addition/subtraction:
Let's get rid of the x terms.
To do this, mult. the first eqn. by -6 and the second by 15. (This is not the only way in which we can do this!!) We get
-90x + 48y = -312
90x +210y = 570
--------------------------
Add all 3 columns together. We end up with:
258y = 258, so y = 1. You can find x by subst. 1 for y in either of the given equations.

Answer:
what do you need help with exactly
Step-by-step explanation:
Answer:
the radius if the measurement of the circle for the center
3/1 or just 3. The highest number divisible by the denominator (bottom number) and numerator (top number) is 6, so 18 divided by 6 is 3 and 6 divided by 6 is 1. That gives 3/1, or just write 3.
Answer:
I believe the answer is 30 coins
