Answer:
x=9
Step-by-step explanation:
3x + 25 = 2(4x – 10)
3x + 25 = 8x-20
3x-8x=-20-25
-5x=-45
5x=45
x=9
Naomi has 43 red beads. 7 white beads times 6 equals 42. 42 plus 1 equals 43. Sometimes you just need to guess and check using common sense. Otherwise an equation would be x+(6x+1)=50, which would be 7x+1+50. Then you simplify to 7x=49 and get x=7. Then multiply by 6 and add 1 to get 43
No,because no other number can be multiplied with 6 to get 85
