Given:
To Find:
Solution:
As here in Question we are given Surface area of cube is 150 sq. feet. So, firstly we have find the side of edge of cube. Let 'a' be the edge of the cube
We know that,
Substituting the required values,
Now,
Hence,
The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, If the given equation is and
.
Step-by-step explanation:
The given is,
...............................(1)
...............................(2)
Step:1
Solution can be obtained by Elimination method,
Equation (1) is multiplied by (-1) ( Eqn (1) × -1 )
..............................(3)
Substrate the equation (1) and equation (3),
( - )
we can cancel the minus because it is available in both sides,
x = 4
From the value of x, Equation (2) becomes,
(Value of y in terms of x)
Where, x = 4
Step:2
Check for solution,
.....................................(2)
Substitute the values of x and y,
4 + 4 = 8
8 = 8
Result:
The values of (x,y)=(4,4). In terms of x, the value y(x)=8-x, where x=4. If the given equation is and
