Salutations!
Two times the sum of number 5 is 20
This will be your equation ---
[tex]2(x+5)=20[/tex]
Brackets indicate multiplication, therefore multiply 2 to the brackets
[tex]2(x+5)=20[/tex]
[tex]2x+10=20[/tex]
[tex]2x=20-10[/tex]
[tex]2x=10[/tex]
[tex]x=10/2[/tex]
[tex]x=5[/tex]
Hope I helped (:
have a great day!
