With our problem, (5x+4)+(-8x-2), we need to get x by itself, and to do that we need to use the order of operations. So (5x+4)+(-8x-2) would actually be -3x-2. To get x by itself, simply divide by -3 on both sides, and you’ll end up with x=2/3

HELP PLEASE!!!
VMariaS [17]

Answer:

Neither

Step-by-step explanation:

First, you need to put your equations in y=mx+b form

Your first equation...

5x + 4y = 3

4y = 3-5x

y = -5/4x + 3/4

Your second equation...

5x-4y = -3

-4y = -5x -3

y = 5/4x + 3/4

The slopes aren't the same and are not reciprocals, so the answer would be neither.

Lapatulllka [165]

Answer:

  • 5.

Step-by-step explanation:

<u>From left to right:</u>

  • 1 1/2 + 1 * 2 + 1 1/2
  • = (1 1/2) + (1 * 2) + (1 1/2)
  • = 1 1/2 * 2
  • = 3 1/2 + 1 1/2
  • = 5.
<h2>Hence, 5 is your answer.</h2>

(don't listen to the other ways. this should be correct).
