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

a.
x + 3a = 5a
x + 3a - 3a = 5a - 3a
x = 2a

b.
4p - 2x = 10p
4p - 4p - 2x = 10p - 4p
-2x = 6p
x = 6p/-2
x = -3p

c.
3y - 6b = 14b + 12
3y - 6b + 6b = 14b + 12 + 6b
3y = 20b + 12
y = 20/3 b + 4

d.
8y - 4m = 12m - 20
8y - 4m + 4m = 12m + 4m - 20
8y = 16m - 20
y = 2m - 5/2
