[tex]\text{Hey there!}[/tex]
[tex]\text{Simplify the expression 8x + x. }[/tex]
[tex]\text{First, you have to combine your like terms (8x \& x)}[/tex]
[tex]\text{x by itself is understood as a(n) \bf{invisible 1}}[/tex]
[tex]\text{Your new equation is: 8x + 1x}[/tex]
[tex]\text{8x + 1x = 9x because 8 + 1 equals 9 \& the x's are the like terms we had to}[/tex] [tex]\text{substitute into the equation}[/tex]
[tex]\text{Thus, your answer is: \boxed{\bf{9x}}}\checkmark[/tex]
[tex]\text{Good luck on your assignment and enjoy your day!}[/tex]
