Hey there!
[tex]Answer:\boxed{x=25}[/tex]
[tex]Explanation:[/tex]
[tex]x-(12-x)=38[/tex] Equation
x - (12 - x) = 38 Simplify both sides
x + -1(12 - x) = 38 Distribute negative
x + (-1)(12) + -1(-x) = 38
x + -12 + x = 38
(x + x) + (-12) = 38 Combine the like terms
2x + -12 = 38
2x - 12 = 38
2x - 12 + 12 = 38 + 12 Add 12 to both sides
2x = 50
50/2 = 25 Divide both sides by 2
x = 25
Hope this helps!
