Question

suma a trei numere a b c si este76 se stie ca a=8 iar b=ax6 care este al treilea numar

Answer 1

a + b + c = 76

a = 8

b = a × 6

b = 8 × 6

b = 48

c = 76 - ( 8 + 48 )

c = 76 - 56

c = 20

Answer 2

$a + b + c = 76 \\ a = 8 \\ b = a \: \times 6 \\ b = 8 \times \: 6 \\ b = 48 \\ 48 + 8 + c = 76 \\ c = 76 - 48 + 8 \\ c = 76 - 56 \\ c = 20 \\8 + 48 + 20 = 76$
