Question

substitution method 2x-y=3 4x+y=3​

Answer 1

Step-by-step explanation:

2x−y=3 ------- (1)

4x+y=3 ------ (2)

From equation 1 :

y=2x−3

Substitute the value of y in equation 2 :

4x+y=3

4x+2x−3=3

6x=3+3

X=

6

6

=1

Now, Substitute x=1 in equation 1 :

2x−y=3

2(1)−y=3

2−3=y

Y=−1

Therefore the solution is: x=1 and y=−1

Answer 2

Answer:

2x-y+4x+y=6

6x=6

x=1

4x+y=3

4+(-1)=3

y=(-1)
