3x+7=19
-7 -7
which cancels out 7 and leaves you with
3x=12
you then divide both sides by 3 to get
x=4

1/2x-1=5
+1 +1
which cancels out 1 and leaves you with
1/2x = 6
you then divide both sides by 1/2 leaving you with
x=12
sorry if this answer is a little late

Answer:

5.63

Step-by-step explanation:

Angle NLM is equal to KLM - KLN.

Since KLM = 137° and KLN = 47°, NLM = °90. (Maybe it doesn't look like a right angle, but the math doesn't lie.)

Since NLM = 16y, then 90 = 16y.

Dividing both sides by 16, we find that:

y = 5.625
