Explicație pas cu pas:
(340 + 26 x h : 4 + 47) : 100 = 1 + 3 = 4
340 + 26 x h : 4 + 47 = 4 x 100 = 400
26 x h : 4 = 400 - 340 - 47 = 13
26 x h = 4 x 13 = 52
h = 52 : 26 = 2
(340+26xh:4+47):100=1+3
(340+26xh:4+47):100=4
340+26xh:4+47=4x100
340+26xh:4+47=400
387+26xh:4=400
26xh:4=400-387
26xh:4=13
26xh=13x4
26xh=52
h=52:26
h=2
