Answer:
2x-8 = 20-6x
Step-by-step explanation:
The distributive property tells us to multiply the term outside parentheses by everything inside:
2(x-4) = 5(4-2x)+4x
2(x)+2(-4) = 5(4)+5(-2x)+4x
2x-8 = 20-10x+4x
Combining like terms on the right gives us
2x-8 = 20-6x

Problema Solution
There were 155 people at the basketball game. Tickets for the game are $2.50 for students and $4 for adults. If the total money received for admission was $492.50, how many students and adults attended the game?
Answer provided by our tutors
let
s = the number of student tickets sold
a = the number of adult tickets sold
there were 155 people at the basketball game
s + a = 155
the total money received for admission was $492.50
2.50s + 4a = 492.50
by solving the system of equations
s + a = 155
2.50s + 4a = 492.50
we find
s = 85 students
a = 70 adults
