Question

Solve.
Eight times the sum of a number and -168 amounts to -64. Find the number.

13
-29
160
-176

Answer 1

Numerical data: 8(x + (-168)) = -64

8(x -168) = -64

First: eliminate parenthesis - use Distribution.

8(x) + 8(-168) = -64
8x + (-1344) = -64
8x - 1344 = - 64

Sec: combine "like" terms - add 1344 with both sides (when you move a term to the opposite side, always use the opposite sign).

8x - 1,344+1,344 = - 64+1,344
8x = -64+1,344
8x = 1,280

Third: isolate "x" - divide both sides by 8.

8x/8 = (1,280)/8
x = (1,280)/8
x = 160

Answer 2

First, write out the problem: 8(n -168)= -64

Simplify: 8(n -168)= -64 is the same as 8n -1344= -64

Divide 8n - 1344= -64 by 8, it gives you: n-168= -8

Add 168 to each side: n -168 + 168 =n, -8 + 168 =160

n = 160

Answer 3

8(x-168)= -64

-64/8=x-168

-8+168= answer 160

Answer 4

Hi, you would first distribute the 8 to the n and -168
8(n-164)=-64

8n-1344=-64
+1344 +1344

8n=1280
Divide the 8

1280/8 =160

n=160

Answer 5

let the number be x
According to the problem.
8(x-168)=-64
or,8x-1344= -64
or,8x= -64+1344=1280
or,x=1280/8
=160
The number is 160

Answer 6

let x be the number
8x-168=-64 add 168 to both sides
8x=104 divide both sides by 8
x=13

Answer 7

Answer is 160.
160 + -168 = -8
8 * -8 = -64

Answer 8

8 * (x + (-168) ) = -64
8 * (x - 168) = -64
x - 168 = -8
x = 160

Answer 9

8 ( x - 168) = -64

8x - 1344 = -64

8x = 1280

x = 160

160 is your answer.
