Question

determina valoarea necunoscutei 556-(8×t+4):(9+9:9-0)=2×3×4×2

Answer 1

556-(8t+4):(9+9:9-0)=2*3*4*2
556-(8t+4):10=48
numitorul comun10
5560/10+(-4-8t)/10=48
(-8t-4+5560)/10=48
[(5560-4)-8t]/10=48
(5556-8t)/10=48
inmultim cu 10 ambele parti
10*(5556-8t)/10=10*48
5556-8t=10*48
5556-8t=480
8t=5556-480
8t=5076
t=5076/8
impartim ambele parti la 4, si avem :
t=1269/2
