Answer:
x = 14
Step-by-step explanation:
∠A = (8x – 12) and ∠B = (6x + 14)
∠A = ∠B because they are vertical angles
then:
(8x – 12) = (6x + 14)
reduce:
2x = 28
x = 14

B is the answers for the question
Answer: x = -8 ; y = -6
Step-by-step explanation:
1*x-2*y=4
1*x = 4 + 2*y
x = 4 + 2*y
Now you replace the value of x on the following equation:
-1*x+10*y=8
-1*(4 + 2*y) = 8
-4 - 2*y = 8
-2*y = 8+4
-2*y = 12
y = -12/2
y = -6
You replace the value of y in the previous equation:
x = 4 + 2*y
x = 4 + 2*(-6)
x = 4 - 12
x = -8

PLZ MARK ME AS BRAINLIST...
Step-by-step explanation:
THE RIGHT ANSWER OF THIS IS RIGHT TRIANGLE....
5x - 4 = -3x + 12.
move -3x to the other side
sign changes to +3x
5x+3x-4= -3x+3x+12
5x+3x-4= 12
move -4 to the other side
sign changes to +4
5x+3x-4+4= 12+4
8x= 16
divide by 8 for both sides
8x/8= 16/8
x= 2
Answer: x= 2
