K is the midpoint of Line JL, JL=4x-2 and JK=7. find X

ipn [44]

X=4. If k is the midpoint then JK is equal to KL. Since JK is 7 then KL is also 7 meaning JK is 14. JK is represented by the expression 4x-2 so you just set that expression equal to 14 and solve for x. Hope this helped!

PLEASE HELP AND SHOW WORK!!

> multiply the second equation by 2 and add it to the first equation.
2(-6x - 7y = -10)
-12x -14y = -20

8x + 14y = 4
-12x - 14y = -20
--------------------
- 4x + 0 = - 16
x = -16/-4
x = 4

> use x = 4 in either equation to find y
8(4) + 14y = 4
32 + 14y = 4
14y = 4 - 32
14y = -28
y = -28/14
y = -2

________________________________

Step 1:

$\frac{{y}^{12} }{ {y}^{12} }$

Wright the equation

________________________________

Step 2:

${y}^{12 - 12}$

Transfer the power of y ie ¹² up to subtract it

________________________________

Step 3:

${y}^{0}$

by subtracting the powers we get 0
