#### how to write a matrix A+2B=c as an equation in terms of x ??

how to write a matrix A+2B=c as an equation in terms of x , where A=(2 -3

-2 5)

and B=(4 3x

0 -1)

and C= (10 -15

So the Matrices are A+2B=C then the first number in A + the first number in B times 2 should = C.

So if you are trying to solve for x you need to note that x in in the top right section of the B matrix, so all of the numbers you are going to use will be in the top right section.  that being said use the equation below.

A=-3, B=3x, C=-15. Plug in these numbers to your initial equation of A+2B=C

-3+2(3x) = -15

distribute the 2:        -3 + 6x = - 15

Add 3 to both sides:   3-3+6x = -15 + 3       simplify:   6x = -12

get x by itself by dividing both sides by 6:    (6x)/6 = -12/6  Simplify:

x=-2

To verify that you have the correct answer plug (-2) in for x in the equation.

-3+2( 3(-2) ) = -15

-3+2(-6) = -15

-3+(-12) = -15  or -3-12 = -15

-15 = -15  Both sides are equal when you plug in our answer for x so x=-2 is correct.

Asked by Shanyia from Monroeville, AL

If a line is vertical it only has one x value and it has an infinite amount of y values.

The equation for a vertical line is X=b

So, take your x value from you x,y coordinate and plug it in for 'b'

So x=3
