Since y = x+5, we can substitute y for x+5, making the new equation
3x + x+5 =25. Now, you can solve traditionally. 4x = 20, x = 5, y = 10
5 because you go down 1, right 5 , and move 0

The answer is ten but what is the unit
We have been given that the length of an edge of a square pyramid is 7 and altitude of the pyramid is 12. We are asked to find the volume of the pyramid.
We will use volume of pyramid formula to solve our given problem.
, where,
b = Area of base of pyramid,
h = Height of pyramid.
We know that area of a square is square of its side length, so area of the base of pyramid would be 
.
The height of the pyramid will be equal to altitude.
Therefore, the volume of the given pyramid would be 196 cubic units and 3rd option is the correct choice.
