Solve for the unknown by using the additive inverse. type the full answer in the box, without using any spaces (ex., x=5).

–x + 4 = –2x – 6

x=(-10)

Step-by-step explanation:

ok, so the first step is to organize the equation: on the left we will put the X numbers, and on the right normal numbers, like this:

-X+2X=-6-4

(p.s I hope that you know that when you transfer numbers and other values,the sign changes : from plus to minus and vise versa)

so now, if you will do the simple math,you will find the value of X.

X=(-10)

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
