Point M is the midpoint of segment JK. Find JK when JM=6x-7 and MK=2x+3.
Whitepunk [10]
If M is the midpoint of JK then JM+MK=JK and JM=MK
so
6x-7=2x+3
minus 2x both sides
4x-7=3
add 7 both sides
4x=10
divide both sides by 4
x=\frac{10}{4}
x=\frac{5}{2}

sub back

JM=6x-7
JM=6(\frac{5}{2})-7
JM=\frac{30}{2}-7
JM=15-7
JM=8

JM=MK=8
JM+MK=8+8=16=JK

x=\frac{5}{2} and JM=8=MK and JK=16
