5n=20 is the equation 5 times n equals 20
Answer:
x-7
Step-by-step explanation:
unknown number = x
<span>Let x be the number of members on the football team.
Let y be the number of members on the basketball team.
equation 1: y = x - 30
equation 2: (x + 10) / (y + 10) = 3 / 2
2 * (x+10) = 3 * (y+10)
Let's replace y with x - 30.
2 * (x+10) = 3 * (x - 30 + 10)
2x + 20 = 3x - 60
x = 80
y = x - 30 = 80 - 30 = 50
The football team has 80 members.
The basketball team has 50 members.</span>
