I NEED HELP Check all the equations.
8 = j – 4
the quotient of a number and two
k + 46
Twelve is the sum of a number and six.
30y
5x = 45

8=j-4     the quotient of a number and two=n/2

12=j

Step-by-step explanation:

Twelve is the sum of a number and six.=n+6=12, n=6

k plus forty six (k+46)

y multiplied by 30 (30y)

5x=45=

x=9

sorry the answers are mixed up

{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

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1

multiply then divide
