Question
Find the value of x and the length of AB if B is the midpoint of AC.
Hint:
Midpoint is the point which divides the line in two equal parts.
The correct answer is: x = 2.5
Step by step explanation:
○ Given:
AB = (2x + 9)
BC = (6x - 1)
○ Step 1:
○ As we know, the midpoint divides the line segment in two equal parts.
So,
As B is midpoint of AC
∴ AB = BC
2x + 9 = 6x - 1
9 + 1 = 6x - 2x
10 = 4x
x = 
x = 2.5
- Final Answer:
x = 2.5.
○ Step 1:
○ As we know, the midpoint divides the line segment in two equal parts.
So,
As B is midpoint of AC
∴ AB = BC
2x + 9 = 6x - 19 + 1 = 6x - 2x10 = 4xx = x = 2.5Related Questions to study

Finding the answer to the given linear equation is the act of solving a linear equation. One of the algebraic techniques for solving a system of two-variable linear equations is the substitution approach. As the name suggests, the replacement method involves substituting a variable's value into a second equation. As a result, two linear equations are combined into one linear equation with just one variable, making it simple to solve. As an illustration, let us swap the value of the x-variable from the second equation and the y-variable from the first equation. By solving the problem, we can determine the value of the y-variable. Last but not least, we can solve any of the preceding equations by substituting the value of y. This procedure can easily be switched around so that we first solve for x before moving on to solve for y.
