Answer:
Step-by-step explanation:
x+y+x+11=y
Combine x and x to get 2x.
2x+y+11=y
Subtract y from both sides.
2x+11=y−y
Combine y and −y to get 0.
2x+11=0
Subtract 11 from both sides. Anything subtracted from zero gives its negation.
2x=−11
Divide both sides by 2.
x= -11/2

Answer:
x=-1
Step-by-step explanation:
The axis of symmetry is along the vertex
The vertex is at (-1,-2)
The x coordinate is -1
x=-1
The solution is a=4
-2(1+5a)=-6(a+3)
-2-10a=-6a-18
+18 +18
16-10a=-6a
+10a +10a
16=4a
divide by 4
4=a
x is 3. you would subtract 19 from 22 to get your answer
