Answer:

x = 7

Step-by-step explanation:

Solve for x over the real numbers:

(3 x)/(2 x - 2) = 14/8

14/8 = 7/4:

(3 x)/(2 x - 2) = 7/4

Cross multiply:

12 x = 7 (2 x - 2)

Expand out terms of the right hand side:

12 x = 14 x - 14

Subtract 14 x from both sides:

-2 x = -14

Divide both sides by -2:

Answer:  x = 7

3x + 1
VMariaS [17]

Answer:

The length of XY is 32

Step-by-step explanation:

Notice that you have a bisector segment (that divides the segment XY  into two equal parts.

since these parts are equal, they must satisfy:

3 x + 1 = 8 x - 24

so, let's solve for x, grouping terms with x on the right of the equal sign, and numerical terms on the left:

1 + 24 = 8 x - 3 x

25 = 5 x

then x = 25/5 = 5

then,now you can find the length of XY as the addition of both parts:

3 x + 1 + 8 x - 24 = 3 (5) +1 + 8 (5) - 24 = 16 + 16 = 32
