2x + 90 + x + 60 - x = 180
2x + 150 = 180
2x = 180 - 150
2x = 30
x = 15
check..
2x = 2(15) = 30
90
15
60 - 15 = 45
30 + 90 + 15 + 45 = 180
180 = 180 (correct)
Answer:
So there are 8 red and 5 brown M&M
Step-by-step explanation:
Let X is red M&M
Let Y is brown M&M
We know that:
- 3 more red M&Ms than brown <=> X = Y +3
- A bowl contains 13 red and brown M&Ms <=> X + Y = 13
substitute X into the second equation: (Y + 3) + Y = 13
<=> 2Y = 10
<=> Y =5
=> X = 5 + 3 = 8
So there are 8 red and 5 brown M&M
