Given the numerical statement:
The product of a number and 3 is equal to 15 minus twice the number
This can be written in numerical expression as,
3x = 15 - 2x
Determine the number.
Solution:
We can solve for the number by solving for the value of x. Start first by transposing -2x on the other side of the equation, note that when transposing a number, the sign changes.
3x = 15 -2x
3x + 2x = 15
5x = 15
Divide both sides by 5 in order to get the value of x
x = 3
Final answer:
The missing number is 3.
