Question

K is the midpoint of J and L, then find x.
Given: JK = 5x - 3
KL = 3x + 1

Answer 1

`x=2`

Explanation:

K is the midpoint of J and L, so

JK = KL.

`5x-3=3x+1`

Add 3 to both sides:

`5x-3+3=3x+1+3`

`5x=3x+4`

Subtract 3x from both sides:

`5x-3x=3x+4-3x`

`2x=4`

Divide 2 on both sides:

`(2x)/(2)=(4)/(2)`

`x=2`
