First what I do is take separate x's and y's inside the ( ) then I like to put the x's and y's off to the side so then if you take 6+12 you get 18 but you have to multiply by 1/2 or divide by two and you get 9 that means that the answer is A because one of the y's is + the other is -

Twice the larger of two consecutive integers is equal to fifteen less than three times the smaller. Find the integers.
Alexxandr [17]

Answer:

17,18

Step-by-step explanation:

let the smaller integer be "a" and the larger be "b"

Then 2b = 3a -15              ........................equ 1

but they are consecutive integers, b= a+1 ; substitute b into equ 1,thus,

2(a+1) = 3a - 15

2a + 2 = 3a-15

collect like terms,

2+15 =3a-2a

17 = a

b= a+1

b = 17+1

b=18.

The integers are 17,18

Solve the equation. 6 = 2(x + 8) - 5x<br> A. 2/3 <br> B. 3 1/3 <br> C. - 2/3 <br> D. -3 1/3
Zinaida [17]
6 = 2(x+8) - 5x
⇒ 2x+ 2*8 -5x= 6
⇒ (2x -5x)+ 16= 6
⇒ -3x = 6 -16
⇒ -3x = -10
⇒ x= -10/(-3)
⇒ x= 10/3
⇒ x= 3 1/3

The correct answer is B. 3 1/3~
