Question

Tentukan penyelesaian dari persamaan 1/5 (m–1)= 1/2(m+2)
Mintak tolong banget yaaa.........

Answer 1

1/5 ( m - 1 ) = 1/2 ( m + 2 )
2 ( m - 1) = 5 ( m + 2 ) [Dikalikan 10]
2m - 2 = 5m + 10
-10 - 2 = 3m
-12 = 3m
m = -4

Answer 2

1/5 m-1/5=1/2 m+1
10(1/5 m-1/5)=10.(1/2 m+1)
2m-2=5m+10
2m-5m=10+2
-3m=12
m=-4
