Question
Use Substitution to solve each system of equations :
X = -Y + 3
3X - 2Y = -1
Hint:
find y by substituting x (in terms of y) in the equation and find x by substituting value of y in the equations.
The correct answer is: x=1 and y =2 is the solution of the given pair of equations.
Ans :- 
Explanation :-
— eq 1
—- eq 2
Step 1 :- find y by substituting 
in eq 2.
Y = 2
Step 2 :- substitute value of y and find x
x = 1 and y = 2 is the solution of the given pair of equations
