Let x = original $, then Jason has x + 50 and Jessica has x - 50.

x + 50 = 5(x - 50)

Solve for x and multiply that by 2.

Sorry, I forgot that this was fourth grade.

x + 50 = 5(x - 50)

Get rid of parenthesis by multiplying the right side by 5 = 5x -250

x +50 = 5x - 250

Add 250 and subtract x from both sides.

300 = 4x

Divide both sides by 4 and then multiply the answer by 2.
