You need to use substitution, to do so, you isolate one of the variables x or y in one equation, and then you substitute that equation into the other.
Since you only need to find x, isolate the y in one of the equations
x - 2y = 4
y = 
Plug this in and simplify
9x + 2y = 16
9x + 2() = 16 Distribute the 2
9x + x - 4 = 16
10x = 20
x = 2 Your answer is C
Answer:Volume = 108 cm ³
Explanation:For a square pyramid, the volume can be calculated as follows:
Volume =
* area of base * height
Volume =
* side² * height
We have:
side length = 6 cm
height = 9 cm
Therefore:
Volume =
* 36 * 9 = 108 cm ³
