忘了方程怎麼解了~麻煩大大指點一下~ (1)8y-34=2y=10 (2)y+2=3(4-y)
最佳解答:
(1) 8y - 34 = 2y - 10 8y - 2y = 34 - 10 6y = 24 y = 24 ÷ 6 y = 4 (2) y + 2 = 3(4-y) y + 2 = 3×4 - 3y y + 2 = 12 - 3y y + 3y = 12 - 2 4y = 10 y = 10 ÷ 4 y = 2.5
其他解答:
第一題我唔係好肯定 如果 8y-34=2y 8y－2y＝34 y=5.666667 又有可能 8y-34=10 8y-2y=10 y=5.5 (2) y+2=3(4-y) y+2=12-3y y+3y=12-2 4y=10 y=2.25 if you want to find me you can find me at facebook chingpang2
