tigry1 [53]

Answer: $x=\dfrac{25}{3}$

Step-by-step explanation:

The given equation : $\log_2(3x+7)=5$

Using logarithmic property : $\log_a N=M\to N=a^M$

The given equation will be equivalent to $(3x+7)=2^5$

$\Rightarrow\ 3x+7=32$

Subtract 7 from both sides , we get

$3x=25$

Divide both sides by 3 , we get

$x=\dfrac{25}{3}$

Hence, the solution is $x=\dfrac{25}{3}$

Use the model to solve for x.

Vitek1552 [10]

Answer:No solution
Explanation: There is no solution because x was eliminated in the last step of solving for x. Since we were left with x not being available to equal three, it shows it’s a no solution problem. Hope this helped!
