Solve the following equation

200+20y=400-30y

Solve for y

200 + 20y = 400 - 30y

Group variables

Group our variables 20y and -30y
add 30y to both sides

20y + 200 + 30y = -30y + 400 + 30y

Cancel -30y on the right side:

50y + 200 = 400

Group constants

Group our constants 200 and 400.
subtract 200 from both sides

50y + 200 - 200 = 400 - 200

Cancel 200 on the left side:

50y = 200

Divide each side of the equation by 50

50y
50
=
  
200
50

y = 4

Final Answer

y = 4





What is the Answer?
y = 4
