HELP I NEED HELP WE BARELY STARTED LEARNING THIS

The Answer to the first one is x = 2. Here's an explanation so you can try and solve the others.

Step-by-step explanation:

First, y = x + 2. Meaning we can substitute the y in 2y. So, we get:

For the next equation:

Since both equations equal y, you must put them side by side.

With the 3rd one just substitute x in 3x with the equation it provides you with (y + 1) and solve (like in the first one).

Same thing with the last one (solve like the second one, side by side), since both equations equal y.

Hope this helps!!

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.
