Answer:

y = 6

x = 2

Step-by-step explanation:

y = 3x

y = x + 4

y = 3x

3x = x + 4

y = 3x

2x = 4

y = 3x

x = 2

y = 3(2)

x = 2

y = 6

x = 2

since both are equal to y they are equal to each other

3x = x + 4

2x = 4

x = 2

also

x = y/3

and

x = y - 4

so

y = 3 (y - 4) or 3y - 12

12 = 2y

y = 6

answers:

x = 2

y = 6
