Y = 3x-2/4 + x alin sa sumusunod ang katumbas ng x? A 2y + 1, B 5y + 2/3, C4y + 8/1-y, D 4y + 2/3-y, E 2 + 1 / y

Sagot:

# (4y + 2) / (3-y) hanggang (D) #

Paliwanag:

# y = (3x-2) / (4 + x) #

# "multiply magkabilang panig ng" 4 + x #

#rArry (4 + x) = 3x-2 #

# rArr4y + xy = 3x-2larrcolor (asul) "ipamahagi ang kaliwang bahagi" #

# rArrxy-3x = -2-4ylarrcolor (asul) "mangolekta ng mga tuntunin sa x sa kaliwa" #

#rArrx (y-3) = - (2 + 4y) larrcolor (asul) "factor out x" #

#rArrx = - (2 + 4y) / (y-3) larrcolor (asul) "hatiin ng" (y-3) #

#rArrx = - (2 + 4y) / - (3-y) larrcolor (asul) "factor out - 1" #

# rArrx = (4y + 2) / (y-3) hanggang (D) #
