Answer:
To solve the equation 2(x - 10) = 90, we can start by simplifying the equation:
2x - 20 = 90
Next, we can isolate the term with x by adding 20 to both sides of the equation:
2x = 90 + 20
2x = 110
Finally, we can solve for x by dividing both sides of the equation by 2:
x = 110 / 2
x = 55
Therefore, the solution to the equation is x = 55.
