This indicates the line is horizontal with equation y = c

Solve by elimination 2x-3y=2 -2x-y=-26
Kisachek [45]

Answer:

x= 10, y= 6

Step-by-step explanation:

2x -3y= 2 -----(1)

-2x -y= -26 -----(2)

(1) +(2):

2x -3y -2x -y= 2 -26

-4y= -24

y= -24 ÷(-4)

y= 6

Substitute y= 6 into (1):

2x -3(6)= 2

2x -18= 2

2x= 18 +2

2x= 20

Divide both sides by 2:

x= 20 ÷2

x= 10

Answer:  0.6 in 10 % ; 0.4 in 15 %

Step-by-step explanation:

1. (x*10%) + (y*15%)/ x+y=12%

2. x+y = 1  x= 1-y

(0.1x + 0.15y/ x+y= 12/100) * 100

(10x + 15y/x+y = 12)*(x+y)

10x+15y= 12x + 12y

-2x=-3y

2x = 3y   2(1 - y)= 3y

2-2y=3y   2= 5y

y= 0.4

x= 0.6
