Answer:
Equation x(6+6)=3(10+x)
x=3.33
Step-by-step explanation:
Form an equation:
x(6+6) The result of 6+6 is multiplied by x, so you would put 6+6 in a bracket (you do what's inside the bracket first in BODMAS) and the x on the outside so you times the result by x.
3(10+x) The number x is added to 10 and the result is multiplied by 3, so the 10+x would go in a bracket with 3 on the outside.
These equal each other, so you would put an equals sign between it to make:
x(6+6)=3(10+x)
Solve to find x:
12x=30+3x You expand the brackets to make this.
9x=30 You would move 3x to the other side by doing the inverse and taking away 3x from 12x.
x=3.33 To get x you would have to do 30 divided by 9 which is 3.33.
Hope this helps :)
Answer: x = 8
Explanation:
Let the unknown number be x
Thus:
6x + 6 = 3(x + 10)
6x + 6 = 3x + 30
3x = 24
x = 24/3 = 8
Therefore x = 8
Explanation:
Let the unknown number be x
Thus:
6x + 6 = 3(x + 10)
6x + 6 = 3x + 30
3x = 24
x = 24/3 = 8
Therefore x = 8
