Answer:

x = 12

Step-by-step explanation:

(10x - 20)° and (6x + 8)° are on the straight angle and they are both equal 180°

to find the value of x:

10x - 20 + 6x + 8 = 180

10x + 6x = 180 + 20 - 8

16x = 192

x = 192/16

x = 12

one number is equal to two times a second number. two times the first number plus two times the second number is 24. if you let

ziro4ka [17]

X = 2y
2x + 2y = 24
So if x = 2y that means 2x = 4y. Which means that 2x + 2y = 24 can be written as 4y + 2y = 24. Simplified to 6y = 24. Now we need to get 1y so we divide both sides by 6, 6y/6 = y and 24/6 = 4. so y = 4. so x= 2y can be written as x = 8.
