five reduced by twice a number is two find the number
Let's call the number "x". According to the problem, five reduced by twice "x" is equal to two.
So, the equation would be:
5 - 2x = 2
To solve this equation, we can isolate "x" by moving the constants to the other side of the equation:
-2x = 2 - 5
Simplifying the right side:
-2x = -3
Now, divide both sides by -2 to solve for "x":
x = -3 / -2
Simplifying the right side:
x = 3/2
Therefore, the number is 3/2 or 1.5.
Let's solve the problem step-by-step.
Step 1: Assign a variable to the unknown number.
Let's assume the unknown number is "x".
Step 2: Write down the given equation.
"Five reduced by twice a number is two" can be written as:
5 - 2x = 2
Step 3: Solve the equation for the unknown variable.
To do this, we need to isolate "x" on one side of the equation.
Subtract 5 from both sides of the equation:
5 - 2x - 5 = 2 - 5
-2x = -3
Finally, divide both sides of the equation by -2 to solve for "x":
(-2x) / -2 = (-3) / -2
x = 3/2
So the number that satisfies the equation is 3/2 or 1.5.
