Tentukan nilai x dan y dari persamaan persamaan berikut a.x+3a=5a.b.4p-2x=10p.c.3y+6b=14b+12.d.8m-4y=12m-20

a) x+3a = 5a
x = 5a-3a
x = 2a
b) 4p-2x = 10p
-2x = 10p - 4p
-2x = 6p
x= -3
c) 3y+6b = 14b+12
3y = 14b - 6b+12
3y = 8b+12
y = 8/3b + 4
d) 8m-4y = 12m-20
-4y = 12m-8m-20
-4y = 4m-20
-y = -1m+5
y = 1m-5
