Let x be the number of 5 points question.
Let y be the number of 2 points question.
Total number of questions is 38
x + y = 38
Total points is 100
5x + 2y = 100
x + y = 38 ------------- (1)
5x + 2y = 100 ---------(2)
From (1):
x + y = 38
x = 38 - y -------------- sub into (2)
5(38 - y) + 2y = 100
190 - 5y + 2y = 100
3y = 90
y = 30 ------------------ sub into (1)
x + 30 = 38
x = 38 - 30
x = 8
There are 8 5-point questions and 30 2-point questions
Step-by-step explanation:
3x + (2x + 4) is equivalent to (3x + 2x) + 4
because there is no change of signs taking place as there is no (-) sign in front of the brackets
3x + (2x + 4) | (3x + 2x) + 4
3x + 2x + 4 | 3x + 2x +4
5x + 4 | 5x + 4
