To simplify the expression, follow the order of operations (PEMDAS/BODMAS):
121 ÷ 11 + 3 ∙ 4 ÷ 2
First, perform the division:
= 11 + 3 ∙ 4 ÷ 2
= 11 + 12 ÷ 2
Next, perform the multiplication:
= 11 + 6
Finally, perform the addition:
= 17
The simplified expression is 17.

To simplify the expression, distribute the 21 to the terms inside the parentheses:
21(x - 4) + 2
= 21x - 84 + 2
= 21x - 82
The simplified expression is 21x - 82.

To solve the equation 5x - 102 = 13, you need to isolate the variable x.
First, add 102 to both sides of the equation:
5x - 102 + 102 = 13 + 102
5x = 115
Next, divide both sides of the equation by 5:
5x/5 = 115/5
x = 23
The solution to the equation is x = 23.
