Answer:
[tex]x=10[/tex]
Step-by-step explanation:
Three times a number increased by ten equal to twenty less than six times a number. Let the number be [tex]x[/tex].
[tex]3x + 10 = 6x-20[/tex]
Add [tex]-6x[/tex] and [tex]-10[/tex] on both sides.
[tex]3x-6x = -20-10[/tex]
[tex]-3x=-30[/tex]
Cancel the negative signs on both sides.
[tex]3x=30[/tex]
Divide [tex]3[/tex] on both sides.
[tex]x=30/3[/tex]
[tex]x=10[/tex]
