Answer:
Option A is correct.
Step-by-step explanation:
Given System of equation are:
y = -3x + 7 ..............(1)
y = 2x - 8 ..........(2)
We have to find the solution of the system of equation.
We use substitution Method,
value of y from equation (1) put in eqn (2),
-3x + 7 = 2x - 8
-3x - 2x + 7 = -8
-5x = -8 - 7
-5x = -15
x = 3
Now put value of x in eqn (1),
y = -3(3) + 7 = -9 + 7 = -2
So, ( x , y ) = ( 3 , -2 )
Therefore, Option A is correct.
