Answer:

x = -1 AC = 9

Step-by-step explanation:

x+10 = 5 + 2x+6

x+10 = 2x+11

-x = 1

x = -1

AC = ×+10 = (-1)+10= 9

5+2(-1)+6 = 9

Answer:

x = -1

ac = 9

Step-by-step explanation:

5 + 2x + 6 = x + 10

2x - x = 10 - 5 - 6

x = -1

ac= 5 + 2 (-1) + 6 = 5 - 2 + 6

= 9

You simply divide both sides by -3.4 to get x=-6.32



if that's not right then just get on a calculator and calculate by doing what I said to divide
