If the product of a number and -4 is subtracted from the number, the result is 3 more than the number. Find the number
lesya [120]

Answer: The number is 0.75 or 3/4

Step-by-step explanation:

let x = the number.

Now set up an equation: The product of a number (x) and -4 = -4x. So -4x is subtracted from the number - x.     x-(-4x)

Then, that equals 3 more than the number (x) = x+3

So the equation is x-(-4x)=x+3.

Then, solve the equation!

x-(-4x)=x+3

x+4x=x+3  (Distribute the negative to the parentheses)

5x=x+3  (Combine like terms)

4x=3  (Get the Xs on one side by subtracting x from both sides)

x=0.75 or 3/4  (divide by the coefficiant, 4, on both sides)
