Question

What is the solution to the equation x - 5 = 15?x = 25x = 20x = 10x = 5

Answer 1

What is the solution to the equation x - 5 = 15

`\begin{gathered} x-5=15 \\ add\text{ 5 to both side} \end{gathered}`
`\begin{gathered} x-5+5=15+5 \\ x=20 \end{gathered}`

Therefore the correct answer is 20

Hence the answer of x = 20
