The number of videos will be 3 and the number of CDs will be 2.
<h3>What is an expression?</h3>
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Christine went shopping and bought each of her five nephews a gift, either a video costing $14.95 or a CD costing $16.88. She spent $78.61 on the gifts.
The number of the videos and CD will be calculated by forming an equation:-
14.95x + 16.88y = 78.61
From heat and trial, we put x = 3 and y = 2 then calculate.
14.95 x ( 3 ) + 16.88 x ( 2 ) = 78.61
44.85 + 33.76 = 78.61
78.61 = 78.61
Therefore, the number of videos will be 3 and the number of CDs will be 2.

Answer:
Step-by-step explanation:
x=81
63+36+x=180
99+x=180
99+81=180
y and z both equal 81
13+y+z=180
180-13=167
167/2 is 83.5
13+83.5+83.5
13+167
180
