✔ 最佳答案
1. 2y = 3y - 10, y = ?.3y - 2y = 10 →
5y = 10 →
y = 10 / 5 →
y = 2.
2. 4 + 2y = 10, y = ?.
2y = 10 - 4 →
2y = 6 →
y = 6 / 2 →
y = 3.
3. y - 2 + 2y = 10, y + ?.
y + 2y = 10 + 2 →
3y = 12 →
y = 12 / 3 →
y = 4.
希望可以幫到你!

1.2y=3y-10
10= 3y-2y
10 =y
2.4+2y=10
2y=10-4
2y=6
y=3
3.y-2+2y=10
3y-2 =10
3y = 10 +2
y = 12/3
y =4
10= 3y-2y
10 =y
2.4+2y=10
2y=10-4
2y=6
y=3
3.y-2+2y=10
3y-2 =10
3y = 10 +2
y = 12/3
y =4

1. 2y = 3y-10
3y - 2y = 10
y = 10
2. 4+2y =10
2y = 10-4
2y = 6
y = 3
3. y-2+2y = 10
y+2y = 12
3y = 12
y = 4
3y - 2y = 10
y = 10
2. 4+2y =10
2y = 10-4
2y = 6
y = 3
3. y-2+2y = 10
y+2y = 12
3y = 12
y = 4
