Point What is the solution to the following equation?
4x+1 = 21
A. X=5
B. X = 11
X = 8
O D. x = 4

Hey there! :)

A. x = 5.

Step-by-step explanation:

Starting with:

4x + 1 = 21

Subtract 1 from both sides:

4x + 1 - 1 = 21 - 1

4x = 20

Divide both sides by 4:

4x/4 = 20/4

x = 5.

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!
