Since we need to find x, we need to move 19 to the other side:
2x + 19 = 0
-19 -19
Which turns into:
2x = -19
Now, we need to divide each side by 2 in order to leave x by itself:
2x = -19
—— ——
2 2
Which will get us:
x = -9.5
And that will be your answer. (Not sure if it’s correct, but I tried lol)
