Given:


y=3x-5\text{ and y=-6x+4}

Aim:

We need to find the solution to the given system of equations.

Step-by-step explanation:

Consider the equation y =3x-5.

Substitute y =-6x+4 in the equation y =3x-5.


-6x+4=3x-5

Solve for x.

Add 6x to both sides of the equation.


-6x+4+6x=3x-5+6x


4=3x-5+6x


4=9x-5

Add 5 to both sides of the equation.


4+5=9x-5+5


9=9x

Divide both sides by 9.


(9)/(9)=(9x)/(9)
x=1

Substitute x =1 in the equation y =3x-5.


y=3(1)-5
y=-2

The solution of the given system of equations is x=1 and y =-2.

Final answer:


(1,-2)
