2х - Зу = 17
3х – Зу = 18
a. (1,45)
b. (7,– 1)
с. (1,1)
d. (-1,-5)

Step-by-step explanation:

2х - Зу = 17

+

3х – Зу = 18

= 5x=35

5x/5=35/5

X=7

2(7)-3y=17

14-3y=17

-14. -14

-3y=3

-3y/3=3/-3

Y=-1

So x =7 and x= -1

Hope this helps

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
