What unknown number makes these equations true 353-203 = 353-200-
To find the unknown number that makes the equation true, we can start by simplifying each side of the equation step by step.
Let's begin with the left side of the equation:
353 - 203 = 150
Now, let's simplify the right side of the equation step by step:
353 - 200 - x
First, we subtract:
353 - 200 = 153
Now, we have:
153 - x
To make this equation true, we need to find the value of x that makes the left side equal to the right side. In this case, we have:
150 = 153 - x
To solve for x, we want to get rid of the 153 on the right side. We can do this by subtracting 153 from both sides of the equation:
150 - 153 = -x
Simplifying this further:
-3 = -x
To solve for x, we need to isolate it on one side of the equation. We can do this by multiplying both sides by -1:
-3 * (-1) = x
Multiplying -3 and -1 gives us:
3 = x
Therefore, the unknown number that makes the equation true is x = 3.
