x=8 is the correct answer. First you had to subtract by 5 from both sides of equation, and it gave us, $\frac{x}{4}+5-5=7-5$ . And then simplify, and it gave us, $\frac{x}{4}=2$ . Then you can multiply by 4 from both sides of equation, and it gave us, $\frac{4x}{4}=2*4$ . And finally simplify, and it gave us the answer is 2*4=8, or x=8 is the correct answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
