The number in the question that gives 28 after the operations is; <em><u>3</u></em>
We are told that the product of seven and the sum of a number and 1 is 28.
Let the number be x. Thus;
7(x + 1) = 28
Use division property of equality to divide both sides by 7.
7(x + 1)/7 = 28/7
(x + 1) = 4
Use subtraction property of equality to subtract 1 from both sides to get;
x + 1 - 1 = 4 - 1
x = 3
Therefore, in conclusion the number is 3.

Answer:
Step-by-step explanation:
F(x)=-3(x)+4
Therefore this implies that we must put the -4 where we see an X on the equation
F(-4)=-3(-4)+4
