ANSWER
The solution is 
EXPLANATION
We want to solve the simultaneous equations

and
.
We substitute equation (2) in to equation (1), to obtain

This has now become a linear equation in a single variable
.
We solve for x by grouping like terms.


We divide through by negative 3 to get;
.
Hence, the solution is 
Answer:
4 1/12 sq. ft
Step-by-step explanation:
To know the amount of area that Pete’s bed have more than Fluffy’s bed, we simply calculate the area of both beds then subtract the smaller from the larger.
The area of Fluff’s bed would be 3 * 21/12 = 63/12 Sq ft
The area of Pete’s bed would be 4 * 28/12 = 112/12 sq ft
The difference in area is thus: 112/12 - 63/12 = 49/12 = 4 1/12 sq. ft
