Y = 2x + 3
y = 3x - 1

 x= 4 and y= 11

Step-by-step explanation:

The problem to solve is:

y = 2x + 3 (equation 1)

y = 3x - 1 (equation 2)

Since y = 3x - 1 Solve x from equalution 1

3x - 1 = 2x + 3

3x - 2x = 3 + 1

x = 4

Since x is 4, solve for y

y  = 3x - 1

y = 3(4) - 1

y = 12 -1

y = 11

x =4 and y =7

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
