Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
-4 - x = -13
Step 2: Solve for <em>x</em>
<u>Add 4 to both sides:</u> -x = -9
<u>Divide both sides by -1:</u> x = 9
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 - 9 = -13
-13 = -13
Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.
-5x + y = 13 ⇒ y = 5x + 13
Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :
-3x + 3y = 3 ⇒ -3x + 3 (5x + 13) = 3
Simplify and solve for x :
-3x + 15x + 39 = 3
12x = -36
x = -3
Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give
-3 (-3) + 3y = 3
9 + 3y = 3
3y = -6
y = -2
So the solution to the system of equations is (x, y) = (-3, -2).

You must force restart the chromebook. It is probably a school computer so you wont be able to get the software/extenstions back. Sadly there is nothing you can do. If you have another computer you can use Chrome remote desktop to connect to it and control it.
