Answer:

Step-by-step explanation:

soulution:

        given,              2x +2x = 16 <em>-</em> <em>2x</em> + 3y = 14

                                 2x <em>+ 2x</em> = <em>-2y </em>+3y = 14 -16

                                       4x = y = -2

                                         y = 4x = -2

                                          y = x =  4/-2

                                         x = y = <u><em>-2 ans</em></u>

Find the value of the expression:2a(b−c)+b(2c−2a)+4c(0.5a−0.5b)
Agata [3.3K]

Answer:

0

Step-by-step explanation:

2a(b−c)+b(2c−2a)+4c(0.5a−0.5b)

To simplify this we need to remove the parenthesis

Distribute 2a, b and 4c inside the parenthesis

2ab -2ac + 2bc - 2ab + 2ac - 2bc

now we combine like terms'

2ab - 2ab becomes 0

-2ac +2ac becomes 0

+2bc - 2bc becomes 0

So final answer is 0
