First, we can simplify the left side. (6+8x)/2 is equal to 3 + 4x. We can put the equation together at this point.
3 + 4x = 5x
we can subtract 4x from both sides to get our final answer,
3 = x, or x = 3. :)
2(12+18) is not equivalent to 24+18
Answer: Third Option
Step-by-step explanation:
We have the following exponential equation
We must solve the equation for the variable x
To clear the variable x apply the 
function on both sides of the equation
Simplifying we get the following:
To simplify the expression 
we apply the base change property
This means that:
Then:
You could convert them into improper fractions first. 7 7/8 should become 63/8 and 3 1/4 should become 13/4. Then, change both fractions so they share a common denominator. I'll use 8.
63/8-26/8 = 37/8, which is then converted into 4 5/8.
Hope that helped you.
