What is 2a+a+2a+a ????

Hello there!

Whenever you see a variable (letter) without a number in front of it, the "number" would be 1!

Example:

a = 1a

So simply do basic math! For now, ignore the letters!

2a + a + 2a + a

becomes

2 + 1 + 2 + 1

Once you have your answer, simply add an a to the end!

Your answer will have NO exponents because you're adding! If you were multiplying or dividing the variables, then exponents would be an issue.

Hope this helped! :)

Answer:

D) (0, -3)

Step-by-step explanation:

The solution of two linear equations is the point of intersection of their graphs.

From the graph, the point of intersection of the graphs of the two linear equations is on the y-axis. So, the $x$ value on the $y$ axis is always 0. Also, the point is below the x-axis. So, the $y$ value of the point will be negative.
