Answer: x=10
Step-by-step explanation: We need to isolate the variable x on one side of the equation.
First, simplify the equation by combining like terms.
The terms -10 and +50 can be combined to give us +40. So, the equation becomes:
14x + 40 = 180.
Next, we have to get rid of the constant term (+40) on the left side of the equation. To do this, we subtract 40 from both sides of the equation:
14x + 40 - 40 = 180 - 40.
This simplifies to: 14x = 140.
We can solve for x by isolating it. To do this, we divide both sides of the equation by 14: 14x/14 = 140/14.
This simplifies to:
x = 10.
