1)JK=KL
5x=3x+2
2x=2
x=1
2)m
m
3)BD=BC+CD
4x=2x+11+24=2x+35
4x-2x=2x+35-2x
2x=35
x=35/2=17.5
BD=4x17.5=70

1. If K is the mid-point JK = KL
5x = 3x + 2; x = 1
JK and KL = 5
JL = 10
2. m
3. 2x + 11 + 24 = 4x
35 = 2x
x = 17.5
BD = 70

1. JK = KL
5x = 3x + 2
x = 1
JK = 5, KL = 5, JL = 10
3. BD = BC + CD
4x = 2x + 11 + 24
2x = 35
x = 35/2
BD = 4x
BD = 4 * 35/2
BD = 70
