Answer:
28
Step-by-step explanation:
Answer:
Solve by substitution
[y=5/2x-4]
[y= -x+3]
Substitute y = -x +3
[-x+3=5/2x-4]
Isolate x for -x+3=5/2x-4: x=2
For y = -x+3
Substitute x = 2
y= -2+3
Simplify
y=1
The solutions to the system of equations are:
y=1 x=2

Answer:50.27
Step-by-step explanation:
The matrix equation has no solution because the same matrix of equal magnitude and opposite in nature is been added to it.
Given to us
A + [11 17 -8 13] = [0 0 0 0]
<h3>What is the value of matrix A?</h3>
We know that the given matrix will give values as zero if the same matrix is been deducted from it, therefore,
A + [11 17 -8 13] = [0 0 0 0]
A = [0 0 0 0] - [11 17 -8 13]
A = [-11 -17 +8 -13]
Thus, the matrix is equal to [-11 -17 +8 -13].
<h3>why this matrix equation has no solution?</h3>
The matrix equation has no solution because the same matrix of equal magnitude and opposite in nature is been added to it, therefore, [11 17 -8 13] is been added to it.
Thus, the sum of the two matrices has no solution.
