So first you multiply 2 and 4x to get 8x. Then you multiply 2 and 5 to get 10. So the problem will look like:

8x+10=90

Then you subtract 10 on both sides of the problem to get:

8x=80

And then divide 8 on both sides to get

x=10

8x+10=90
-10. -10
8x=80
divide both sides by 8
x=10

Which expression is equivalent to 15 n=10 (n+3/n)?

Answer:

±√6

Step-by-step explanation:

$15n=10(n+\frac{3}{n} )$ is your expression first muiltiply out the 10 to get 15n= 10n+10 3/n next subtract 10 n from both sides to get 5n=10+3/n multiply both sides by n to get 5n^2=13 combine both sides and use the quadratic equation to solve to get your solution of ±√6
