For your equation, you will need to [tex]{\underline{\underline{{subtract}}}[/tex] their combined ages by half of 23.
[tex]\text{Half of 23 is 11.5}[/tex]
[tex]\text so\;23 - 11.5 = 11.5[/tex]
[tex]\text{We need to check our answer.}[/tex]
[tex]11.5 + 11.5=23[/tex]
[tex]\bold{So\;our\;answer\;is\;going\;to\;be}[/tex]
[tex]\huge\text{11.5}[/tex]
[tex]\rule{300}{1.0}[/tex]
