if 10 is less than a number is multiplied by 3, the result is equal to 2 times the number. What is the number?
2 answers:
Let the number be x.
3(x - 10) = 2x | 10 less than x multiply be 3 equal 2 times x
3x - 30 = 2x | Distribute 3
x - 30 = 0 | Subtract 2x from both sides
x = 30 | Add 30 to both sides
Answer: The number is 30.
Hello!
We know that
(x - 10) * 3 = 2x
Distribute the 3
3x - 30 = 2x
Subtract 2x from both sides
x - 30 = 0
Add 30 to both sides
x = 30
The answer is 30
