Answer:
one solution with a y value of 5
Step-by-step explanation:
/| x+y-4 = 0| x-y-6 = 0
We try to solve the equation: x+y-4 = 0
x+y-4 = 0 // - x-4
y = -(x-4)
y = 4-x
We insert the solution into one of the initial equations of our system of equations
We get a system of equations:
/| x+x-6-4 = 0| y = 4-x
2*x-10 = 0 // + 10
2*x = 10 // : 2
x = 10/2
x = 5
We insert the solution into one of the initial equations of our system of equations
For y = 4-x:
y = 4-5
y = -1
We get a system of equations:
/| y = -1| x = 5
ANSWER
EXPLANATION
The dimensions of a matrix is of the form:
The dimensions of the first matrix is
The dimensions of the second matrix is
Since the inner products are the same,the outer products give the dimensions of the product of the two matrices.
Therefore the dimensions of the product is a 2×2 matrix.
