kaakk mohon bantuannya nomer 11 & 13 untuk ulangan harian besok

11) ->2*3x+5=1/16
->2*3x+5=16*-1
->2*3x+5=2*4.-1
->2*3x+5=2*-4

=> 3x+5=-4
=>3x=-5+-4
=>3x=-9
=>x=-9/3
=>x=-3 (C)

13) 3*x+2= ³√3*4x+2
3*x+2=3*(1/3)4x+2
3*x+2=3*(4x+2)/3

=>x+2=(4x+2)/3
=>(x+2)3=4x+2
=>3x+6=4x+2
=>3x-4x=2-6
=>-x=-4
=>x=4 (C)
