Tyreese is using algebra tiles to solve the equation below.
2x + 5 = -x + (1)
answers
a. remove one x-tile from both sides. b. remove two x-tiles from the left side. c. add one positive x-tile to both sides. d. add two positive x-tiles to both sides.

for this case we have the following equation:

To resolve:

We add x to both sides of the equation:

We subtract 5 on both sides of the equation:

We divide between 3 on both sides of the equation:

We add x to both sides of the equation

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
