12 = 5x - 13x - 44

Please help me

eorder the terms:

12 = -44 + 5x + -13x

Combine like terms: 5x + -13x = -8x

12 = -44 + -8x

Solving

12 = -44 + -8x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8x' to each side of the equation.

12 + 8x = -44 + -8x + 8x

Combine like terms: -8x + 8x = 0

12 + 8x = -44 + 0

12 + 8x = -44

Add '-12' to each side of the equation.

12 + -12 + 8x = -44 + -12

Combine like terms: 12 + -12 = 0

0 + 8x = -44 + -12

8x = -44 + -12

Combine like terms: -44 + -12 = -56

8x = -56

Divide each side by '8'.

x = -7

Simplifying

x = -7

i dont know

step-by-step explanation:

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
