Answer 1

Pasos a seguir:

1. Mover la variable.
2. Agrupar términos semejantes.
3. Dividir ambos lados entre el número ubicado del lado izquierdo.

A) 3d = 15 d =

3d — 15d = 0

— 12d = 0

d = 0

B) 6a + a = 77 a =

7a = 77a

7a — 77a = 0

— 70a = 0

a = 0

C) 35b - b = 306 b =

36b = 306b

36b — 306b = 0

— 272b = 0

b = 0

D) 96a - 17a = 60a + a =

79a = 61a

79 — 61a = 0

18a = 0

a = 0

E) a/7 = 4 a =

a = 28a

a — 28a = 0

— 27a = 0

a = 0

F) m/9 = 9 m =

m = 81m

m — 81m = 0

—80m = 0

m = 0

G) x/25 = 38 x =

x = 950x

x — 950x = 0

— 949x = 0

x = 0
