Answer:

x = 1 , y = 4

Step-by-step explanation:

3x = y + 1

=> y + 1 = 3x

=> y = 3x - 1

y = 3 + x

Substituting y = 3x + 1 in y = 3 + x,

=> 3x + 1 = 3 + x

=> 3x - x = 3 - 1

=> 2x = 2

=> x = 2/2

=> x = 1

y = 3 + x

Substituting x = 1,

=> y = 3 + 1

=> y = 4

Answer:

x=2

y=5

Step-by-step explanation:

y=3x

replace it in 3x=y+1

so"

3x= 3+x+1

3x-x=4

2x=4

x=2

so now we replace x=2 in y=3+x

which gives:

y=3+2

y=5
