b) x/[} 5&-1 0&2/3 ]=2[3 0]

To solve the equation , we need to multiply both sides of the equation by the inverse of the matrix on the left side.The inverse of a matrix is denoted as and satisfies the equation , where is the identity matrix.In this case, the matrix on the left side is . To find its inverse, we can use the formula for the inverse of a 2x2 matrix: where .Applying this formula, we get: Now, we can multiply both sides of the equation by : Performing the matrix multiplication, we get: Therefore, the solution to the equation is .
