Answer: 14
= 16 x (7/8)
= 8 goes into 16 2 times
= 2 x 7
= 14
X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.
You should pat a total of $90.44
You would use, Order of Operations, A.K.A PEMDAS.
Parenthesis, Exponets, Multiplication, Division, Addition, Subtraction
Follow that order and you do the work yourself, you would never learn by asking other's for the answer. >:)
