To find the solution to the equation 3x - 7 = 25, we need to isolate the variable x.
We can solve this equation by performing inverse operations to eliminate the constant term and isolate the variable.
Here are the steps to solve the equation:
Step 1: Add 7 to both sides of the equation to cancel out the -7 on the left side:
3x - 7 + 7 = 25 + 7
3x = 32
Step 2: Divide both sides of the equation by 3 to isolate the variable x:
3x/3 = 32/3
x = 32/3
Now let's simplify the solution:
Step 3: Divide 32 by 3:
x = 10.6667
Since the given options are whole numbers, we need to round our solution to the nearest whole number.
Rounding 10.6667 to the nearest whole number gives us 11, which is not one of the options given.
Therefore, the correct answer is d) None of these.
It's important to note that the given equation 3x - 7 = 25 does not have a whole number solution. If there were any decimal options in the given choices, we could have chosen the closest one to 10.6667 as the solution. However, in this case, none of the options match the exact solution.
Therefore, the correct answer is d) None of these.
