Answer

The equation written to the specifications of this statement is given as: $4x - 8 = 56$ The solution is: $x = 16$

Work Step by Step

The product of $4$ and a number can be translated to: $4x$ We subtract $8$ from this to get: $4x - 8$ The word "is" means "equals," so "is 56" translates to: $= 56$ We combine both sides of the equation to get: $4x - 8 = 56$ The first step to solving this equation is to add $8$ to both sides to get: $4x = 64$ We then divide each side by $4$ to get $x$ by itself: $x = 16$
