Try it on paper first. A hint, the key idea and the worked solution are here when you need them.
A designer moves a shape by the matrix equation $3X - 2
=
X$.
A matrix of order has rows and columns, and is in row , column . Equal matrices have equal entries in the same places. Add matrices of the same order entry by entry. A scalar multiple multiplies every entry.

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Isolate . $3X =
+ 2
=
$.
Step 2. Divide by . $X =
$.
Check. $3X =
2
$.
Answer: $X =
$.
