Hurry i will mark !
emma read the statement “the quotient of six and a number, x, is the same as negative two times the difference of x and 4.5.” she translated it as shown below.

6x = -2x - 4.5

what errors did emma make? select two options.

a - she should have used division to represent the quotient of six and x.

b - she should not have included an equal sign.

c - she should have used parentheses to show that -2 is multiplied by (x - 4.5)

d - she should have subtracted the difference (x - 4.5) from -2

e - she should have used parentheses to show that -2 is multiplied by (4.5 - x)

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
