Answer:

x=36

Step-by-step explanation:

The 2 angles, ∠EAF and ∠FAB are on a straight line. This means they are supplementary, and add to 180 degrees.

So,

∠EAF +∠FAB =180

We know that ∠EAF is 3x and ∠FAB is 2x, so we can substitute them in

3x+2x=180

Combine like terms

5x=180

Divide by 5 on both sides

x=36

So, x=36 degrees, or the last choice

Answer:

A. 2y = 22

Step-by-step explanation:

You are basically combining like terms. Look at the equation and subtract from top to bottom.

You will subtract 5x and 5x, 4y and 2y, and 25 and 3.

Now you have 0 + 2y = 22.

Removing the 0 (because it is worth nothing), you will be left with 2y = 22 which corresponds to A.
