Carilah nilai X yg benar 1.2(X-4)+4=X-5 2.2(X-7)+4=4X-5 3.1/2(4X-8)+5=X+3 Bantu ya

1. 2(X-4)+4=X-5
2x-8+4 = x-5
2x-x+12 = -5
x = -5-12
x = -17

2. 2(X-7)+4=4X-5
2x-14+4 = 4x-5
2x-10 = 4x-5
2x-4x = -5+10
-2x = 5
x = 5/-2
x = 2 1/-2

3. 1/2(4X-8)+5=X+3
2x-4+5 = x+3
2x-x+1 = 3
x = 3-1
x = 2

semoga membantu yaa:)
