WebAlgebra Matrices Solve the Matrix Equation [ 2 3 4 7] ⋅ [ x y] = [ 1 1] [ 2 3 4 7] ⋅ [ x y] = [ 1 1] Multiply [2 3 4 7][x y] [ 2 3 4 7] [ x y]. Tap for more steps... [ 2x+3y 4x+7y] = [1 1] [ 2 x + 3 y 4 x + 7 y] = [ 1 1] Write as a linear system of equations. 2x+3y = 1 2 x + 3 y = 1 4x+7y = 1 4 x + 7 y = 1 Solve the system of equations. WebFirst, we need to find the inverse of the A matrix (assuming it exists!) Using the Matrix Calculator we get this: (I left the 1/determinant outside the matrix to make the numbers simpler) Then multiply A-1 by B (we can use the Matrix Calculator again): And we are done! The solution is: x = 5 y = 3 z = −2 gold hack for war commander https://pineleric.com

Webyou can add any two n×m matrices by simply adding the corresponding entries. We will use A+B to denote the sum of matrices formed in this way: (A+B) ij = A ij +B ij. Addition of … WebAdding all the elements of a matrix to itself would be the same as multiplying every cell in the matrix by 2, or multiplying the matrix itself by 2. You don't need to worry about the dimensions lining up because you are adding the same matrix to itself, and then you would simply multiply every cell in the matrix by 2. ( 2 votes) Luis Ocasio
