Question

Tolong ya
1.5(y-1)=4y
2.4(3-2y))=15-7y
3.3(2y-3)=5(y-2)
4.8-2(3-4y)=7y-1
5.5x+7(3x+2)=6(4x+1)

Answer 1

1. 5y-5=4y
    y=5
2. 12-8y=15-7y
    y=-3
3. 6y-9=5y-10
    y=-1
4. 8-6+8y=7y-1
    y=-3
5. 5x+21x+14=24x+6
    2x=-8
    x=-4

Answer 2

1. 5y-5 = 4y
    5y-4y = 5
     y = 5

2. 7-8y = 15-7y
     -8y+7y = 15-7
   -y = 8

3. 6y-9 = 5y-10
   6y-5y = -10 +9
   y = -1

4. 6(3-4y) = 7y-1
   18y-24y = 7y-1
   -6y-7y = -1
   -13y = -1

no5 ga begitu paham
