Question

SOLVE FOR A. THANKSSSSSS!!!!!!!!!

Answer 1

Cross multiply 10 and 5 to get 50
now you have 16+a=50
subtract 16 from both sides and you get a=34

Answer 2

So when solving for a, we always need to isolate variables. So we can get rid of 10 by multiplying both sides (which the one with a would cancel it out) because multiplying is the opposite of multiplying. Then we have a+16=50. We can get rid of 16 too by subtracting it, then we know that a=34.
