Solve the Matrix Equation [[-8,-14,-2x]]-([[-19,17,-1]]+[[14,13,-2]])=[[-3,-44,-9]]

$[\begin{array}{c} - 8 & - 14 & - 2 x \end{array}] - ([\begin{array}{c} - 19 & 17 & - 1 \end{array}] + [\begin{array}{c} 14 & 13 & - 2 \end{array}]) = [\begin{array}{c} - 3 & - 44 & - 9 \end{array}]$

Step 1

Matrices can only be multiplied if the number of columns in the first matrix is equal to the number of rows in the second matrix. The matrices cannot be multiplied.

Step 2

Add the matrix to both sides of the equation.

Step 3

Simplify both sides of the equation.

Matrices can only be multiplied if the number of columns in the first matrix is equal to the number of rows in the second matrix. The matrices cannot be multiplied.

Adding the null matrix to any matrix is a matrix itself.

Step 4

Solve.

$- 8 = - 3, - 14 = - 44, - 2 x = - 9$

Step 5

Solve.

$8 = 3, 14 = 44, 2 x = 9$

Solve the Matrix Equation [[-8,-14,-2x]]-([[-19,17,-1]]+[[14,13,-2]])=[[-3,-44,-9]]
