Step-by-step explanation:
Let's find the answer.
Because we have 3 equations and 3 variables (x1, x2, x3) a 3x3 matrix (A) can be constructed by using their respectively coefficients.
Equations:
Eq. 1 : x1 + 2x2 + 5x3 = 5
Eq. 2 : x1 + x2 + x3 = 6
E1. 3 : 4x1 + 6x2 + 5x3 = 7
Coefficients for x1 ; x2 ; x3
From eq. 1 : 1 ; 2 ; 5
From eq. 2 : 1 ; 1 ; 1
From eq. 3 : 4 ; 6 ; 5
So matrix A is:
And the vector of vriables (X) is:
Now we can find the resulting vector (B) using the 'resulting values' from each equation:
In conclusion, AX=B is:
The largest sum of three numbers that meet at a corner is 15
<h3>How to determine the largest sum?</h3>The number cube that completes the question is added as an attachment
The largest number in the number cube is 6.
On the number cube, the next largest numbers share the same corner with the number 6
So, the largest set of numbers on the cube are 6, 5, 4
Add the numbers:
Sum = 6 + 5 + 4
Evaluate
Sum = 15
Hence, the largest sum of three numbers that meet at a corner is 15
