42+30= [blank] (7+5)
Enter the unknown number that makes the equation true.
then what is the answer to it
pus
42+30 = x(7+5)
72 = 12x
To solve this equation, we need to simplify the right side of the equation first.
The expression inside the parentheses is 7+5. Evaluating this expression gives us 12.
So, we can rewrite the equation as:
42 + 30 = [blank] (12)
Now we can solve for the unknown number by performing the arithmetic on the left side of the equation:
42 + 30 = 72
Therefore, the unknown number that makes the equation true is 72.
