Let books =x and games =y
2x+2y=26
4x+1y=28
If you solve for x and y, x=5 and y=8
Step-by-step explanation:

Cameron is 72 inches tall.
2/3 of 72 = 48
Sine = opposite / hypotenuse
If we think of the hypotenuse =1, then sine(C) = x / 1 or just "x"
The sine (A) = adjacent / hypotenuse = y / 1 or just "y"
The three units upward shift is denoted by +3 outside of the parenthesis and horizontal shift to the right is represented by -2 inside the parenthesis.
The answer is C.
