Answer
2x - 7 = 4
Step-by-step explanation:
Answer:


Step-by-step explanation:
Given:
; find x and y.
Let's start with finding x first. Let's distribute the left side of the equation.

Let's move everything we can to the left side of the equation. Some things will cancel out.

Now, let's move the term that includes
to the left side of the equation. Everything else should be moved to the right.

Let's get rid of the negative sign in front of
by dividing both sides by -1.

To get
completely isolated, divide both sides by
.

Simplify.

Let's solve for y. We will start with the distributed and simplified equation to make it easier.

Now, let's move the term that includes
to the left side of the equation. Everything else should be moved to the right.

Again, let's get rid of the negative sign in front of the
by dividing both sides by -1.

To isolate y, divide both sides by z.

Simplify.

A. Or B.
I picked this in one of my questions and I don’t remember which specific one but the one or other should be correct.
12y = -18x -4x
12y = -22 x
x int = (12,0) when y is zero
y int = (0, -22) when x is zero
Answer:
Step-by-step explanation:
the was I understand matrix multiplication, I re-learned tonight so I could be wrong but.....
according to Gaggle matrix multiplication is possible when the number of columns in matrix 1 equals the number of rows in matrix 2
it is called the dot product (that sounds familiar)
first choice has 2 columns and 1 row can't multiple this one
second choice has 1 column and 2 rows can't multiple this one
third choice has 2 columns and 1 row can't multiple this one
fourth choice has 1 column and 1 row This one can be multiplied
