Answer:
To solve a literal equation means to express one variable with respect to the other variables in the equation.
Step-by-step explanation:
1.
Determine which variable you need to isolate. Isolating a variable means getting the variable on one side of an equation by itself.
2.
Use algebra to solve for the desired variable. Use inverse operations to cancel variables on one side of the equation and move them to the other side. 3.
Keep the equation balanced. Whatever you do to one side of the equation, you must also do to the other side
1) Sketching it
Since the line segment AD = 10x -5 and AC= 3x +1 and CD= 15
According to the Segment Addition postulate we can write:
3x+1+15=10x-5 <em>Combining like terms</em>
3x +16 = 10x -5 <em>Subtract 16 from both sides</em>
3x = 10x-5-16 Subtract 10x from both sides
3x-10x =-21
-7x = -21
7x=21 <em>Dividing by 7 on both sides</em>
x=3
the first one the third one and the last
