Paano mo malulutas ang d + q = 31 at 10d + 25q = 5.95?

Sagot:

# d = 51.27 #

# q = -20.27 #

Paliwanag:

Una, pansinin iyan # 10d + 25q = (10d + 10q) + 15q #

at iyon # (10d + 10q) = 10 (d + q) = 10 * 31 = 310 #

Magtatapos ka na:

# 310 + 15q = 5.95 rarr 15q = 5.95-310 rarr q = (5.95-310) /15=-20.27 #

Mula dito, madali mong maisip na:

#d + (- 20.27) = 31 rarr d = 31 + 20.27 = 51.27 #
