The equation simplified (combine like terms) would be 11x+(-24) =180. Since adding a negative is the same as subtracting a positive, you could also write it as this: 11x-24=180. Next step is isolate the variable, so to do that you need to add 24 to both sides of the equation: 11x-24+24=180+24. This is the same as 11x=204. Now to get only one of the variable, you need to divide both sides by 11. x=18.54 repeating or x=18 6/11. Hope this helped!
<span>3x+4+8x-28=180 Add 8x to 3x 11x+4-28=180 Subtract 28 from 4 11x-24=180 Add 24 to both sides 11x=204 Divide 11 on both sides Final Answer: x= 204/11 or 18 6/11 *Both answers are equivalent to each other.</span>
