The solution for the system of equation is (1,-1)
What is system of equations?
A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.
We have
y = 2x-3 . . . . . (1)
y = -x . . . . . . (2)
Put the equation (2) y = -x in equation (1)
-x = 2x - 3
-x - 2x = -3
-3x = -3 ( dividing both side by -3 )
x = 1 ( putting the value of x = 1 in equation (2) ) we get
y = -x
y = -1
we get the points of the equations x = 1, y = -1
hence, option a is correct answer
