\rightarrow \sf 5x + 15 = 28


\rightarrow \sf 5x + 15 -15= 28-15


\rightarrow \sf 5x = 13


\rightarrow \sf (5x)/(5) = (13)/(5)


\rightarrow \sf x = (13)/(5)


\rightarrow \sf x = 2(3)/(5)


\rightarrow \sf x = 2.6

Answer:


  • \boxed{\sf{x=(13)/(5)=2.6 }}

Explanation:

To solve for x, you have to isolate it on one side of the equation.

First, subtract by 15 from both sides.


\sf{5x+15-15=28-15}

Solve.

28-15=13

Rewrite the problem down.

5x=13

Divide by 5 from both sides.


\sf{(5x)/(5)=(13)/(5) }

Solve.

You can also divide the numbers from left to right.

13/5=2.6


\boxed{\sf{x=(13)/(5)=2.6 }}

  • Therefore, the correct answers is x=13/5=2.6.

I hope this helps you! Let me know if my answer is wrong or not.
