the cost of a ride ticket?
1
A Add 5 to both sides.
BSubtract 20 from both sides.

`\huge\text{Hey there!}`

`\huge\textbf{Random note:}`

`\large\textsf{(We will solve for your given question as well because it}\\\large\textsf{pops up in solving for your question.)}`

`\huge\textbf{Solving for your original answer:}`

`\mathbf{5 + 10x = 20}`

`\mathbf{10x + 5 = 20}`

`\huge\textbf{SUBTRACT 5 to BOTH SIDES:}`

`\mathbf{10x + 5 - 5 = 20 - 5}`

`\huge\textbf{Simplify it!}`

`\mathbf{10x = 20 - 5}`

`\mathbf{10x = 15}`

`\huge\textbf{DIVIDE 10 to BOTH SIDES:}`

`\mathbf{(10x)/(10)=(15)/(10)}`

`\huge\textbf{Simplify it!}`

`\mathbf{x = (15)/(10)}`

`\mathbf{x = (15/5)/(10/5)}`

`\mathbf{x = (3)/(2)}`

`\mathbf{x = 1 (1)/(2)}`

`\mathbf{x = 1.5}`

`\huge\textbf{Therefore, the overall answer should be:}`

`\huge\boxed{\star\boxed{\mathsf{\ x= (3)/(2) \ }}\star}`

`\huge\textbf{And to answer your question, the very}\\\\\huge\textbf{first step in solving for this equation}\\\\\huge\textbf{[5 + 10x = 20] is:}`

`\huge\boxed{\textsf{Option D. Subtract 5 to both sides}}\huge\checkmark\\\\\\\\\\\large\text{Look at the explanation above to see how we chose that.}\\\\\large\text{Remember: addition opposite is subtration \& subtraction opposite}\\\large\text{is addition, whereas multiplication is division \& divsion is}\\\large\text{is multiplication.}`
