Answer:
x=-7, y= -20
Step-by-step explanation:
2x - y =6
x - y = 13
when I subract (x-y =13 ) from (2x-y =6)
2x -y =6
-x +y=-13
______________
x = -7
substitute x=-7 in the second equation
-7 - y =13
-y = 13 +7
-Y = 20
Y=-20
x=-7, y= -20
Answer:

Step-by-step explanation:
Remember that complementary angles <em>always </em>add up to 90°.
We know that the two complementary angles are represented by (x) and (x+14). In other words:

So, let's solve for x.
First, combine like terms:

Let's isolate the x by subtracting 14 from both sides:

The left cancels. Subtract on the right:

Divide both sides by 2:

The left side cancels. Divide on the right:

So, the value of x is 38°.
And we're done!
