I think it is a glide reflection.
First you plug in the missing values
y=3 x=4 z=2
3÷2×4-2
than you solve
the answer is 4
<span>See examples for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2</span>
