Y=x+6 and x+y=14 in substitution method ​

(4,10)

Step-by-step explanation:

Since y=x+6, you can put that equation in the other function

x+(x+6)=14

2x+6=14

2x=8

x=4

Now plug in the x value to solve for y

y=(4)+6

y=10

Since x=4 and y=10, the intersection between the 2 lines is (4,10)

y = x + 6

y = - x + 14

+

y + y = x - x + 6 + 14

2y = 20

2y ÷ 2 = 20 ÷ 2

y = 10 & x = 4

20%

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
