equation => 3x + 4 = 2(2x + 1)
The value of x is 2
Step-by-step explanation:
The first segment has length 2x + 1.
The second segment has length 3x + 4.
The second segment is 2 times the length of the first segment. We are asked to find the value of x by setting up and solving an equation.
The corresponding equations is,
3x + 4 = 2(2x + 1)
Since the second segment is 2 times the length of the first segment
3x + 4 = 4x + 2
Combine like terms
3x - 4x = 2 - 4
-x = -2
Multiply both sides by -1
x = 2
Therefore, the value of x is 2
Bonus:
The length of the first segment is
First segment = 2x + 1
First segment = 2(2) + 1
First segment = 4 + 1
First segment = 5
The length of the second segment is
Second segment = 3x + 4
Second segment = 3(2) + 4
Second segment = 6 + 4
Second segment = 10
