NeTakaya

Answer:

  0.05 cm

In a right triangle, 40-x=(3x). What is the value of x?
Archy [21]

Answer:

x=10

Step-by-step explanation:

Let's solve your equation step-by-step.

40−x=3x

Step 1: Simplify both sides of the equation.

40−x=3x

40+−x=3x

−x+40=3x

Step 2: Subtract 3x from both sides.

−x+40−3x=3x−3x

−4x+40=0

Step 3: Subtract 40 from both sides.

−4x+40−40=0−40

−4x=−40

Step 4: Divide both sides by -4.

−4x

−4

=

−40

−4

x=10
