Find the Variables [[0,-2],[0,0]][[x],[y]]=[[1],[0]]

Problem

[[0,−2],[0,0]]*[[x],[y]]=[[1],[0]]

Solution

  1. Perform matrix multiplication on the left side of the equation by multiplying the rows of the first matrix by the column vector.

0*(x)+(−2)*(y)=1

0*(x)+0*(y)=0

  1. Simplify the equations resulting from the multiplication to isolate the variables.

−2*y=1

0=0

  1. Solve for y by dividing both sides of the first equation by −2

y=−1/2

  1. Analyze the variable x by looking at the simplified system. Since x is multiplied by 0 in both equations, its value does not affect the equality.

x∈ℝ

Final Answer

[[0,−2],[0,0]]*[[x],[y]]=[[1],[0]]⇒x∈ℝ,y=−1/2
