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

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
