Answer:
-2 ( 2.1 x +3 y - 1.8 = - 4.2 x -6 y + 3.6
Step-by-step explanation:
Distributive property:-
distributive law
let a , b, c are two real numbers and by using distributive law is
a.(b+c) = a.b + a.c
given -2 ( 2.1 x +3 y - 1.8) = -2 . (2.1)x + (-2).3 y + (-2).(-1.8)
now simplification right hand side
-2 ( 2.1 x +3 y - 1.8 = - 4.2 x -6 y + 3.6
