0 Seventy minus the product of 8 and a number is 86.
Write the verbal sentence as an equation. Then solve the equation
70 - 8x = 86
8x = 16
x = ?
To write the verbal sentence as an equation, let's break it down:
"Seventy minus the product of 8 and a number": Let's denote the unknown number as "x". The product of 8 and a number can be written as 8x. Therefore, "Seventy minus the product of 8 and a number" can be written as 70 - 8x.
Now, the verbal sentence is "Seventy minus the product of 8 and a number is 86."
We can write this as an equation:
70 - 8x = 86
To solve the equation, we need to isolate the variable "x."
Step 1: Start by subtracting 70 from both sides of the equation:
70 - 8x - 70 = 86 - 70
-8x = 16
Step 2: Divide both sides of the equation by -8 to solve for x:
-8x/(-8) = 16/(-8)
x = -2
Therefore, the solution to the equation is x = -2.
