Answer:
y + 2 = 4x...(1)
y = 3x - 1...(2)
Now, by substituting eqn(2) into eqn(1). it becomes
(3x -1) +2= 4x...(3)
Solving eqn(3) for x, we get
3x - 1 + 2 =4x
-1+2=4x - 3x
1 =x
therefore x=1
Now put x=1 into the eqn(1) or eqn (2). That is the equation of your choice
Choosing eqn (1)
y + 2 = 4x
y + 2 = 4(1)
y + 2 =4
y = 4-2
y = 2
