Substitute ( y = 5 ) back into ( x = 14 - y ): [ x = 14 - 5 = 9 ]

Substitute ( x = 14 - y ) into the second equation: [ (14 - y) - y = 4 ] [ 14 - 2y = 4 ] [ -2y = 4 - 14 ] [ -2y = -10 ] [ y = 5 ] solution of ncert

It sounds like you're asking for (likely for Mathematics or Science, for classes 6–12). Since you didn't specify the subject, class, chapter, or exercise , I’ll provide a general structured answer format that follows NCERT solution style — along with a fully worked example. Substitute ( y = 5 ) back into

Check: ( x + y = 9 + 5 = 14 ) ✓ ( x - y = 9 - 5 = 4 ) ✓ solution of ncert
