6х-18=102

6х=102+18

х=120:6

х=20

Answer 3

To solve the equation 5x + x - 18 = 102, we can simplify it by combining like terms:

6x - 18 = 102

Next, we can isolate the variable x by moving the constant term (-18) to the other side of the equation by adding 18 to both sides:

6x - 18 + 18 = 102 + 18

Simplifying further:

6x = 120

To solve for x, divide both sides of the equation by 6:

(6x)/6 = 120/6

Simplifying:

x = 20

Therefore, the correct answer is x = 20.
