To solve this equation, we need to first simplify both sides and then isolate the variable x.

Given equation: 50 + x = 60 + 60x + 40 = 80 + 30

Simplify by combining like terms:

50 + x = 120 + 60x

Next, move the x term to one side of the equation:

-x + 60x = 120 - 50
59x = 70

Finally, solve for x by dividing both sides by 59:

x = 70/59

Therefore, the solution to the equation is x = 70/59 or approximately 1.18644.
