The ScrollView only accepts a View / Layout within it.

I can not be sure but it seems to me that in this case, it should be the first element:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.example.tulio.exercicio5.MainActivity">
    android:layout_width="wrap_content"
    android:layout_height="match_parent">

    <LinearLayout

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"

    ...
    ...
        </LinearLayout>
    </LinearLayout>
</ScrollView>

You will eventually have to adjust the values of android:layout_width and android:layout_height for both ScrollView and the first LinearLayout.

In your case you have 2 children for the scrollview, and the same only accepts a child view for its hierarchy .. I'll give you an example of right and wrong way.

RIGHT

        <?xml version="1.0" encoding="utf-8"?>
    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        tools:context="com.example.tulio.exercicio5.MainActivity">
        android:layout_width="wrap_content"
        android:layout_height="match_parent">

        <LinearLayout
            <LinearLayout>
            </LinearLayout>
            <LinearLayout>
            </LinearLayout>
        </LinearLayout>
    </ScrollView>

Note that we have 3 linear layout within the scrollview, but only one is the direct child of it.

INCORRECT

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.example.tulio.exercicio5.MainActivity">
    android:layout_width="wrap_content"
    android:layout_height="match_parent">

    <LinearLayout
    </LinearLayout>
    <LinearLayout>
    </LinearLayout>
</ScrollView>

If you stop to parse, you will see that the scrollview this time has 2 children LinearLayout, this will cause the error:

a scroll view can only have one child
