Hi there! 

Lets dive into the problem, starting with the equation for volume; length x width x height.

If it's 8 x 12 inches, That means the height is 8 and the length is 12. The side, or width, would be x.

The equation should be 8 times 12 times x, or (8)(12)(x).

3x+y=5<br>2x-2y=-2<br><br>solve by using process of elimination (find both x and y)​
Bingel [31]

Answer:

The value of 'x' is 1 and 'y' is 2. So, the point is (1, 2).

Step-by-step explanation:

Given:

The given pair of linear equations are:

3x+y=5\\2x-2y=-2

In order to solve by elimination method, we have to eliminate any one variable using mathematical operations. Let us eliminate 'y'.

Multiplying the first equation by 2 and adding the result to the second equation. This gives,

(3x+y)\times 2=5\times 2\\6x+2y=10\\2x-2y=-2\\+\\----------\\8x+0=8\\8x=8\\x=\frac{8}{8}=1

Now, the value of 'y' can be calculated by plugging in 1 for 'x' in the first equation. This gives,

3(1)+y=5\\3+y=5\\y=5-3\\y=2

Therefore, the value of 'x' is 1 and 'y' is 2.

The solution is (1, 2).
