well, to figure that out, you need to have an equation with 8n in it. However, 8n is the same as 8xn
8n = 1 n = 1/8
Yes. In algebra, as the multiplication symbol (×) looks very much like an x, it is not written and any two items written next to each other are multiplied together. With 8n this means 8 times n, and n is used to represent a number; thus 8n does indeed mean multiply a number by 8.
8n-5 = 3
In Algebra, "is" means Equal (=).
It is: -3+8n-5 = 8n-8 when simplified
n=10/7. i did this one mentally. but are you sure its 8n minus negative 4n or is it 8n minus 4n? 8n- -4n does not equal 8n-4n 8n- -4n is the same as 8n+4n
3 + 8n = -58n = -8n = -1
"And" in algebra usually means addition.
8n = 160 n = 20
8n + 4n2 -8n
