Answer: X+ 4 + 8x -6 + 13x -21 = 180: x = 203/22 (Decimal: x = 9.22727)
Step-by-step explanation:
1.) x+4 + 8x -6 +13x+ -6 – 21 =180
2.) Then you add similar elements: x + 8x +13x = 22x
22x+4 -6 – 21 = 180
3.) Add 23 to both sides, 22x – 23 + 23 = 180 + 23
4.) Simplify, 22x = 203
5.) Divide both sides by 22, 22x/22 = 203/ 22
6.) Simplify x = 203/22
