Question

Tentukan nilai berikut
1. 2y-y+4 =
2. 2y+7=8+y
3. 8t+10=7t+5
4. 3x-2=2w-5
5. 32-2w=2w-5
6. 3p-44=6+2p
7. 5x+10=15+4x
dengan menggunakan cara

Answer 1

1. y = -4
2. 2y-y = 8-7
y = 1
3. 8t-7t = 5-10
t = -5
4. 3x-2w = -5+2
3x-2w = -3
5. -2w-2w = -5-32
-4w = -37
w = 37/4
6. 3p-2p = 6+44
p = 50

Answer 2

1. 2y-y+4 =0
y+4=0
y=-4
2. 2y+7=8+y
2y-y=8-7
y=1
3. 8t+10=7t+5
8t-7t=5-10
t=-5
4. 3x-2=2x-5
3x-2x=-5+2
x=-3
5. 32-2w=2w-5
2w+2w=32+5
4w=37
w=37/4
w=9,25
6. 3p-44=6+2p
3p-2p=6+44
p=50
7. 5x+10=15+4x
5x-4x=15-10
x=5
