L = Lenny's age
m = Max's age
l = 3m
l - m = 24
3m - m = 24
2m = 24
m = 12
l = 3(12)
l = 36
Lenny's age is 36 and Max's age is 12.
Answer:
Simplifying
2x + -5 = x + -4
Reorder the terms:
-5 + 2x = x + -4
Reorder the terms:
-5 + 2x = -4 + x
Solving
-5 + 2x = -4 + x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
-5 + 2x + -1x = -4 + x + -1x
Combine like terms: 2x + -1x = 1x
-5 + 1x = -4 + x + -1x
Combine like terms: x + -1x = 0
-5 + 1x = -4 + 0
-5 + 1x = -4
Add '5' to each side of the equation.
-5 + 5 + 1x = -4 + 5
Combine like terms: -5 + 5 = 0
0 + 1x = -4 + 5
1x = -4 + 5
Combine like terms: -4 + 5 = 1
1x = 1
Divide each side by '1'.
x = 1
Simplifying
x = 1
Y=4/3x-7/3. I used this website called calculator.net
If you won 2 blue cards, then you lose 3 grey cards
If you won 4 blue cards, then you lost 6 grey cards (multiply by 2)
If you won 6 blue cards, then you lost 9 grey cards (multiply by 3)
If you won 8 blue cards, then you lost 12 grey cards (multiply by 4)
Answer: A) you lost 12 grey cards
Another way to see this answer is to solve the proportion below
2/3 = 8/x
2*x = 8*3
2x = 24
x = 24/2
x = 12
