Question

Use the matrix tool to solve the system of equations. Choose the correct ordered pair.

3x - 4y = -8
7x - 5y = 3

Answer 1

Aight bet.

Answer 2

Do you know how to solve matrix equations/expressions?

Answer 3

Well, since you are offline, you can come back to the answer.

Answer 4

First, add 4y to both sides;

3x - 4y+ 4y= -8 + 4y

Answer 5

Next, you simplify that part.

3x = -8 + 4y

Answer 6

Then, keeping the rule of whatever you do to one side you must do to the other, divide both sides of the equation by 3.

\frac{3x}{3}=-\frac{8}{3}+\frac{4y}{3}

Answer 7

Hm let me type the fraction out.

Answer 8

\[\frac{ 3x }{ 3 } = -\frac{ 8 }{ 3 } + \frac{ 4y }{ 3 }\]

Answer 9

Since we did this after adding 4y, we must simplify!
