M = 135/19 and n = -5/19
You have to give them like terms so that when you eliminate they cancel out and you can solve. The easiest way to do so is by multiplying the top equation by -4 and the bottom by 3.

cuboid
Answer:
Surface area = 96 m^2
Step-by-step explanation:
Let's cube root the volume to find the length of one side of the cube.

Therefore each side is 4 m.
Surface area of one side = 4x4 = 16
A cube has 6 sides.
Total surface area of the cube = 16*6 = 96 m^2
Answer:
