Answer:
x=8
z=132
Step-by-step explanation:
We know that 6x and 4x+16 are vertical angles, so they are equal
6x= 4x+16
Subtract 4x from each side
6x-4x = 4x-4x+16
2x =16
Divide each side by 2
2x/2 =16/2
x =8
We also know that 6x and x form a straight line
6x+z = 180
6(8) + z =180
48+z =180
Subtract 48 from each side
48-48 +z =180-48
z = 132

Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x + 4y = -8
-5x - 4y = -16
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -6x = -24
- Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -x + 4y = -8
- Substitute in <em>x</em>: -4 + 4y = -8
- Isolate <em>y</em> term: 4y = -4
- Isolate <em>y</em>: y = -1
