Answer:

0 = 0

Step-by-step explanation:

2+5x−7=3x−9+2x

Step 1: Simplify both sides of the equation.

−2+5x−7=3x−9+2x

−2+5x+−7=3x+−9+2x

(5x)+(−2+−7)=(3x+2x)+(−9)(Combine Like Terms)

5x+−9=5x+−9

5x−9=5x−9

Step 2: Subtract 5x from both sides.

5x−9−5x=5x−9−5x

−9=−9

Step 3: Add 9 to both sides.

−9+9=−9+9

0=0

PLEASE HELP ME :(<br> God bless.
Dmitriy789 [7]

Answer:

x - 99 ≤ -104 → 2nd line

x - 51 ≤ -43 → 1st line

150 + x ≤ 144 → 4th line

75 < 69 - x → 3rd line

Step-by-step explanation:

Ugh! Wow, this is going to be tedious, thanks alot, bro (jk, I got your back).

x - 99 ≤ -104

 + 99   + 99

x ≤ -5

There should be a line going from -5 to negative infinity (AKA the left) with a FILLED circle. So, the second one is correct.

x - 51 ≤ -43

 + 51   + 51

x ≤ 8

There should be an arrow with a FILLED circle going to negative infinity (AKA the left). So, the first one is correct.

I'm going to take a shortcut and notice that one of the lines has a filled circle while the other one has an empty circle. So the empty circle must relate to the question without a ≤ or ≥, but with a < or >. We see that 75 < 69 doesn't have ≤ or ≥ but a '<.' So this one must have the empty circle, which is on line 3. The last equation has to be on line 4.
