10(2x+-15)= 40x=30 how do i solve this?

if you meant 40x-30 the answer is 9

Step-by-step explanation:

you have to distribute the 10x to 2x and 15

this gives you 20x+150=40x-30

divide 20 into 180

x=9

the square root of what number? if you add that, then someone will probably answer the question.

you already gave the answer
