Answer:
the substitution method is one way to solve linear equation. the substitution method is when substitute the one y value with the other:
example :
x+y=10
y=10-x ( value of y)
2x+y=12 ( substitute the value of y in the equation )
2x+(10-x)=12
2x+10-x=12 ( now solve for x)
x=12-10
x=2 ( substitute the value of x in the equation x+y=10)
x+y=10
2+y=10
y=10-2
y=8

16 m³
Step-by-step explanation:
Step 1:
Here we are going to find the volume of square pyramid.
Volume of square pyramid = 
× 
× 
Here base = 4 m
Height = 3 m
Step 2:
Volume = (1/3) × (4 × 4) × 3
= 16 m³
