More Lessons for Matrices
We can multiply a matrix with a number (also called a scalar
). For scalar multiplication, we multiply each element of the matrix by the number or scalar.
We need to consider only one equation
2k = 6
k = 3
Find the values of x and y.
2x – 6 = 5
2x = 11
x = 5.5
4 – y = 3
y = 1
