Question

1. (9/4 +5-5y)=2(1/3-2y)
2.x-1 1/2= 2 1/3
tolong di jelasin yah

Answer 1

1) (9/4+5-5y) = 2(1/3-2y)
9/4+20/4-5y = 2.1/3 + 2.(-2y)
29/4 - 5y = 2/3 - 4y
-5y+4y = 2/3-29/4 ----> KPK penyebut = 12
-y = 8/12-87/12
-y = -79/12
y = 79/12
y = 6 7/12



2) x-1 1/2 = 2 1/3
x = 2 1/3 + 1 1/2
x = 7/3 + 3/2 ----> KPK penyebut = 6
x = 14/6+ 9/6
x = 23/6
x = 3 5/6
