Equation:
123 = x + 12 + x + 3(12 + x)
Solution:
x = 15
Step-by-step explanation:
Jamil: x
Kiera: 12 + x
Luther: 3(12 + x)
Total: 123 badges
Equation:
123 = x + 12 + x + 3(12 + x)
Solve:
123 = x + 12 + x + 3(12 + x)
123 = x + 12 + x + 36 + 3x
123 = 5x + 48
-48 -48
75 = 5x
/5 /5
15 = x
Therefore, the value of x is 15.
Answer:
x + x+12 + 3(x+12) = 123
x = 15
Step-by-step explanation:
Jamil : x
Kiera : x+12
Luther : 3 ( x+12)
x + x+12 + 3(x+12) = 123
Distribute
x + x+12 + 3x+36 = 123
Combine like terms
5x+ 48 = 123
Subtract 48 from each side
5x+48-48 = 123-48
5x =75
Divide by 5
5x/5 = 75/5
x = 15

Answer:
x=9
Step-by-step explanation:
combine like terms
4+5=9
9+6x=7x
to get 6x with 7x subtract 6x from both sides as its positive
6x-6x=0
7x-6x=x
9=x
x=9
