Answer 1

`\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 2

• 
  `\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.
