Question

Afla nr necunoscut din expresile g)22-5x(38-4xg)=12,.,.,.,h)26+(6xh-7x3):9=27 P.S daca puteti raspunedtimi la amandoua!

Answer 1

g) 22 - 5x(38-4xg) = 12
    5x(38-4xg) = 22-12
    5x(38-4xg) = 10
    38-4xg = 10:5
    38 - 4xg = 2
    4xg = 38-2
    4xg = 36
    g = 36:4
    g = 9

h) 26 + (6xh-7x3):9 = 27
    (6xh - 7x3):9 = 27-26
    (6xh - 21):9 = 1
    6xh-21 = 1x9
    6xh-21 = 9
    6xh = 9+21
    6xh = 30
    h = 30:6
    h = 5
