What is the solution of the system? use the elimination method.−4x−2y=−122x+4y=−12    !

The solution of the equation −4x−2y=−12  , 2x+4y=−12 are (6 , -6) .

Step-by-step explanation:

As given the equations are

−4x−2y = −12

Simplify the equation

-2(2x + y) = -12

2x + y = 6

Another equation

2x+4y=−12

2(x+2y) = −12

x + 2y = -6

Two equation becomes

2x + y = 6

x + 2y = -6

Multiply x + 2y = -6 by 2 and subtracted from 2x + y = 6 .

2x - 2x + y - 4y = 6 + 12

-3y = 18

y = -6

Putting the value of y in the equation

2x + -6 = 6

2x = 12

x = 6

Therefore the solution of the equation −4x−2y=−12  , 2x+4y=−12 are (6 , -6) .

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
