Question 414582: matrix b is the result when matrix a is multiplied by a scalar.
matrix a is a 2 by 2 first row 6 and -45 second row is 12 and -48
matrix b is a 2 by 2 first row -4 and 30 second row is -8 and y
what should be the value of y in matrix b and what is a scalar

Hi

 a = matrix%282%2C2%2C6%2C-45%2C12%2C-48%29 

 b = matrix%282%2C2%2C-4%2C30%2C-8%2C32%29 

scaler (constant that @ term in a is multiplied by to get corresponding term in b) = -2/3

    -4 = k6

    -4/6 = k = -2/3      y =  -48*-2/3 = 32
