Question

3x + y = 5 and 2x + 3y = 1
by substitution method​

Answer 1

Answer:

1 and −1

Step-by-step explanation:

3x+2y=1 ------- (1)

2x−3y=5  ------ (2)

From equation 1:

2y=13x

2y=1−3x

Y=21−3x

Substitute the value of y in equation 2:

2x−3y=5

2x3(21−3x)=5

4x3+9x=10

13x=10+3

X=1313=1

Now, Substitute x=1 in equation 1 :

3x+2y=1

3x1+2y=1

2y=13

Y=2−2

Y=−1

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