Answer:
x=-4 and y=10
Step-by-step explanation:
Use the second equation to make y=x+6
sub y=x+6 into the first equation
-x-2*(x+6)=0
-x-2x-12=0
-3x-12=0
3x=-12
x=-4
Now sub x=-4 into the second equation
-(-4)+y=6
y=6+4
y=10
Answer:
Solution one is correct and solution 2 and 3 are incorrect
Step-by-step explanation:
You simply make an equation because for vertical angles 2 angles that are across from each other have the same value (in this case 2x+30 and 5x-36.)
The equation: 2x+30=5x-36---->3x=66----> x=22
Solution 1 is correct.
