Answer:
AC = 24
Step-by-step explanation:
First you want to set up the equation to find what x equals which is AB + BC = AC
12x - 20 = x + 6 + 5x - 4
Then combine like terms and solve.
12x - 20 = x + 6 + 5x - 4
12x - 20 = 6x +2
+20 +20
12x = 6x + 22
-6x -6x
6x = 22
x = 11/3 or 3 2/3
Then plug in x to the AC equation.\
12(11/3) - 20
44-20
AC = 24
Answer:

N/A
Answer:
x=-1, y=3
Step-by-step explanation:
3x+2y=3
3x-2y=-9
since we have -2y and 2y we can just add the equations
6x=-6
x+0y=-1
x=-1
to solve x using elimination multiply the top equation by -1
-3x-2y= -3
3x-2y=-9
and add
0x-4y=-12
-4y=-12
y=3
and substitute x and y to double; check
3(-1)+2(3)=3
-3+6=3
3=3
checks out so these are correct
