Question

resolva as equações literais na incógnita x : a) 2x-4a=8x / b)4c 3x=12c / c) 4(x-2p)=3x p

Answer 1

a) 2x -4a = 8x
2x -8x = 4a
-6x = 4a . (-1)
x = 4a/6 (simplificamos por 2)
x= 2a/3

b) 4c . 3x = 12 c
12xc = 12c
x = 12c/12c
x= 1

c) 4.(x-2p) = 3x . p
4x -8p = 3xp
4x -3xp = 8p
x (4 -3p) = 8p
x= 8p/4-3p
