Use the substitution method to solve the system of equations. Choose the correct ordered pair.

The ordered pair is(6,2)

Step-by-step explanation:

2x+2y=16_equation1

y=x-4_equation 2

isolate y in(2x+2y=16)

2y=16-2x

divide both sides by 2

y=8-x

substitute y into equation 2

8-x=x-4

8+4=2x

12=2x

divide both sides by 2

x=6

substitute x into equation 1

2(6)+2y=16

12+2y=16

2y=16-12

2y=4

divide both sides by 2

y=2

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
