X + 7 = 23 middle school work

X = 16

Step-by-step explanation:

23 - 7 = 16

16

Step-by-step explanation:

23 - 7 = X

To find X we do the inverse of addition which is subtraction. The 7 cancels out and the 23 becomes a 16. We can even check our answer. 16 + 7 = 23

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
