Answer:

x=-1/2

Step-by-step explanation:

Solving

2x-1+8=6

2x+7=6

2x=6-7

2x=-1

x=-1/2

Checking

put x=-1/2 in equation

LHS 2(-1/2)-1+8

=-1-1+8

Answer: x=-1/2

<u>Simplify both sides of the equation</u>

<u></u>2x+-1+8=6<u></u>

<u></u>(2x)+(-1+8)=6 (Combine Like Terms)

2x+7=6

<u>Subtract 7 from both sides</u>

<u></u>2x+7-7=6-7\\2x=-1<u></u>

<u></u>

<u>Divide both sides by 2</u>

2x/2=-1/2\\x=-1/2
