Select all the expressions that represent a correct solution to the equation 6(×+4)=20
kozerog [31]

Answer:

the solution x = \frac{-2}{3}

Step-by-step explanation:

Given equation is 6 ( x+4) =20

<u>Distributive property</u>:-

a .(b + c) = a .b + a . c

Given equation is 6 ( x+4) =20

by using distributive property  6 .x + 6.4 =20

                                                  6x +24 =20

    subtracting '24' on both sides, we get

                                            6x +24 -24 = 20 -24

                                            6x = -4

dividing by '6' on both sides, we get

                                             \frac{6x}{6} = \frac{-4}{6}

                                            x = \frac{-4}{6}

<u>Final answer</u> :-

the solution of given equation is x = \frac{-2}{3}
