Understanding Algebraic Equations

The video tutorial explains how to solve a math problem where 12 plus X is 8 more than 10. It guides the viewer through setting up the equation, simplifying it, solving for X, and finally calculating the value of 3x. The process involves writing the equation, simplifying it to find x equals 6, and then calculating 3x to be 18.

What equation can be formed from the statement '12 plus X is 8 more than 10'?

• 12 + X = 8

• 12 + X = 18

• 12 + X = 20

• 12 + X = 10
