In a basketball game, the number of points scored by the Miners was equal to 20 less than twice their opponent's score. The total number of points was 127. What was the total score?
Let
x--------> the number of points scored by the Miners
y------> the number of points scored by the opponents
we know that
x+y=127---------> equation 1
x=2y-20-------> equation 2
substitute equation 2 in equation 1
[2y-20]+y=127
3y=127+20
3y=147
y=147/3
y=49 points
find the value of x
x=2y-20
x=2*49-20-----------> x=78 points
therefore
the answer is
The total score is
Miners 78 points
Opponents 49 points
