Answer:
x=3
y=3
Step-by-step explanation:
Given :
To solve : Solution of system of equation
Solution :
---(a)
---(b)
Since we are given that we have to solve these equation by elimination method :
Multiply equation (a) by 2 and equation (b) by 4
Then equation becomes:
Subtract (a) from (b)
Now put this value in (b) to get value of x
Thus the solution of this system of equations is x=3 and y=3
Answer: x = -3, -1/3, 1/2, 3
