Answer 2

Question must be : y=3x;y=2x-1

Answer by step by step :

Solution for y=3x;y=2x-1 system of equations:

/| y-(3*x) = 0| y-(2*x)+1 = 0

We try to solve the equation: y-(3*x) = 0

y-3*x = 0 // + -3*x

y = -(-3*x)

y = 3*x

We insert the solution into one of the initial equations of our system of equations

We get a system of equations:

/| 3*x-(2*x)+1 = 0| y = 3*x

x+1 = 0 // - 1

x = -1

We insert the solution into one of the initial equations of our system of equations

For y = 3*x:  

y = -1*3

y = -3

We get a system of equations:

/| y = -3| x = -1
