The correct answer would be A -2b ^^
HTH ^^
Brainliest would be great is possible! ^^
Okay first you need to combine like terms together (3x and 1x)
7x + 4 = 5 + 4x
now you need x only on one side, you could subtract either 7x or 4x
3x + 4 = 5
subtract 4 over
3x = 1 is the answer
here is a contradiction because in one inequality x can be equal to 15 ; and in the other it cannot
Answer:


Step-by-step explanation:

Edit: Solve for Y
A straight line is 180 degrees so one side (the x side) is 160°, The Y side is 20, and you can work backwards by -

Hi there!
mistake= step 2..
If you can see, the equation is the opposite so this means that to find the answer, your gonna have to add first.. instead of subtracting..
<em><u>1.Add the terms:</u></em>
<em><u /></em>
<em><u /></em>
<em><u>2.Simplifly the terms:</u></em>
<em><u /></em>
<em><u /></em>

<em><u>3.Subtract the terms:</u></em>

Therefore, the mistake was step 2...
