Make a system of equations.


Re-arrange the 2nd equation:

Subtract y to both sides:

Plug in -y + 22 for 'x' in the first equation.


Subtract 3y to both sides:

Subtract 22 to both sides:

Divide -4 to both sides:

Plug this into any of the two equations to find 'x':


Subtract 5 to both sides:

So one of the numbers is 5 and one of them is 17.
82 degrees and 98 degrees
First, find the original equation
180 = (x) + (x + 16)
Simplify: 180 = 2x + 16
Next, use the subtraction property of equality to subtract 16 from both sides
180 - 16 = 2x + 16 - 16
Simplify: 164 = 2x
Then, you can use the division property of equality to find the value of x
164/2 = 2x/2
Simplify: 82 = x
Now, we know that the first angle equals 82 degrees and that the second angle equals 98 degrees
1- distributive property
4- identity property
8- commutative property
