if kl=2x,lm=3x-2 and km=43, what is the value of x?
2x + 3x - 2 = 43
5x = 45
x = ?
If KL = 4x -1, LM = 2x - 1, and KM = 2x, what is the value of x?
If KL = 4x, LM = 3x – 2, and KM = 5, what is KL?
9 right ??
To find the value of x in the given equations kl = 2x, lm = 3x - 2, and km = 43, we can use the information from the equation km = kl + lm.
Substituting the given values, we have:
43 = 2x + (3x - 2)
To simplify, we combine like terms:
43 = 5x - 2
Next, we isolate the variable on one side of the equation:
43 + 2 = 5x
45 = 5x
Finally, we solve for x by dividing both sides of the equation by 5:
x = 45/5
Simplifying, we get:
x = 9
Therefore, the value of x is 9.
