What is the value of x in the equation 1.5(x + 4) - 3=4.5(x-2)

Hi there! The answer is x = 4.

Let's solve this equation step by step!


First we need to work out the parenthesis, which can for instance be done using rainbow technique.


First collect terms.


Subtract 3 from both sides


Subtract 4.5x from both sides.


And finally divide both sides by -3.

Hello!

the answer is:

the correct option:

b.

why?

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!
