Twelve is added to the product of a number and 5. the result is -3. find the number. and write an equation for this. show full !

Let the number be x

Equation:

12 + 5x = -3

The equation is 12 + 5x = -3

Solve it:

5x = -3 - 12

5x = -15

x = -15 ÷ 5

x = -3

The number is -3.

-3

Why?

It's asking for the product of a number (which is unknown, therefore it's "x") and 5 which has 12 added to it. Your equation would be: 5x + 12 = -3

And you subtract 12 from both sides (12 minus 12 is 0 which cancel it out and -3 minus 12 is -5) leaving you with 5x = -15, then you divide by 5 leaving you with X= -3 .
