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:
hmmmmm i think the answer is 7
Step-by-step explanation:
Answer:
4a2−b2−2a+b, there are no factorable rational numbers.
Step-by-step explanation:
A equals 3 because 87 divided by 29 equals 3. You can check this by doing 29 times 3 which equals 87. Hope that Helped!
