Afla x+y+z = pentru : x=(9512-9412)×8 y =4320 -(100×37) -(8×7 ×10 +10) z=19 ×y - 6×2×10

Răspuns :

x=100x8 = 800

y = 4320-3700-570 = 50

z = 19 x 50 - 120 = 830

x+y+z = 800+50+830 = 1680

x= (9512-9412)×8
x=100×8
x=800

y= 4320-(100×37)-(8×7×10+10)
y= 4320-3700-(560+10)
y=620-570
y=50


z= 19×50-6×2×10
z=950-120
z=830

x+y+z= 800+50+830
x+y+z=1.680
