Can someone help with this explain the steps pls

first one is x=-y+11 and the second is x=−y/2 +19/2

Step-by-step explanation:

Step 1 for #2: Subtract y from both sides.

Step 2 for #2: Divide both sides by 2.

Step 1 for #1: Subtract y from both sides.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
