Part A:

x = 6

Step-by-step explanation:

5(x + 2) = 6x + 3x - 14

use the distributive property for the left side of the equation

(in case you don't know, * means multiply)

combine like terms on the right of the equation.

Move the +10 on the left to the right (change the + to a - )

Move the +9x on the right to the left (change the + to a - )

All the like terms are together so now you can combine them.

divide both sides by -4 so the x is by itself

x = 6

Hope this was helpful :-)

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

im pretty sure its
