3x + 4 = 8x - 11
Solve using properties of equality.
check your solution.
x = a

x = 3

Step-by-step explanation:

Step 1. add 11 to both sides

3x + 4 = 8x - 11

    +11         +11

3x + 15 = 8x

Step 2. subtract 3x from both sides

3x + 15 = 8x

- 3x        -3x

15 = 5x

Step 3. divide by 5 to isolate x

15 = 5x

/5     /5

x = 5

step-by-step explanation:

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!
