Equation:
9+3x=30
Answer:
9+3x=30
Subtract 9 from each side.
3x=21
divide by 3 on each side.
x=7

Answer:
Length = 24 and width = 6.
Step-by-step explanation:
2L + 2W = 60 where L = length and W = width.
The length must be in the 20's to make a perimeter of 60, as there's no number in the 10's or 30's that has 2 consecutive even integers and 40 something is impossible.
The only length which fits the given conditions is 24.
Then the width would be (60 - 2(24)) / 2 = (60 - 48) / 2
= 6.
That's the answer.
