<span>3n + 4 = 7
</span><span>3n = 7 - 4
3n = 3
n = 1</span>
Simple! 1/3 times 3 equals 3/3, or 1.
A) -9
-7(x+9)=9(x-5)-14x
-7x-63=9x-45-14x
-45 -45
-7x-18=9x-14x
+7x +7x
-18=9x+7x-14x
-18=2x
(-18)/2=(2x)/2
-9=x
10 = 2x5
4 = 2x2
LCM + 2x2x5 = 20 <=== smallest number of bracelets and hair bow to buy
25 i think, i just used an anagram server to generate it
