Solve for x 8x - 3 = 5 (2x + 1)​

X = -4

Step-by-step explanation:

x = -4

Step-by-step explanation:

First, the pharenthesis: 8x-3 = 5*2x+5*1

8x -3 =10x+5

then take all the Number with x to the left, the ones without to the right, by changing their sign.

8x -10x = 5 +3

-2x = 8

now divide by -2

-2x/-2=8/-2

x=-4

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
