Answer:

150

Step-by-step explanation:

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

50+0.6x=20+0.8x

Step 1: Simplify both sides of the equation.

0.6x+50=0.8x+20

Step 2: Subtract 0.8x from both sides.

0.6x+50−0.8x=0.8x+20−0.8x

−0.2x+50=20

Step 3: Subtract 50 from both sides.

−0.2x+50−50=20−50

−0.2x=−30

Step 4: Divide both sides by -0.2.

−0.2x

−0.2

=

−30

−0.2

x=150
