Solve 10x-3(x-7)=x+39

** Combine like terms ↓ **

** Subtract 21 from both sides ↓**

** Subtract x from both sides ↓ **

**Divide both sides by 6 ↓*

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!

answer is : muchas/tipicas

have a nice day!
