Question

Five times the sum of a number and 7 equals 3

Answer 1

Hi there! :)
Let the number be x. Thus, the sum of a number and 7 would be x + 7. We can now set up the equation as follows:
5(x + 7) = 3;
5x + 35 = 3;
x = -32/5

Answer 2

The answer or number that you are looking for is -6.4. You can get this by dividing 3 by 5 which is equal to 0.6. Next you would subtract 7 to reverse the act of having added it. This will give you -6.4 which is what you are looking for.
