Question

r
- 3y = 8; 3x + y = 2
5x - 3y = 8... (1)
3x + y = 2... (II)​

Answer 1

Answer:

x = 1

y = -1

Step-by-step explanation:

1------- 5x-3y=8

2-------3x+y=2

let me take 2nd eqn

y=2-3x....(3)

sub 3 in 1

5x-3(2-3x)=8

5x-6+9x=8

14x-6+6=8+6

14x=14

x=14/14

x=1

y=2-3(1)

y=2-3

y=-1

Answer 2

Answer:

Consider the equation 3x+y=2

Multiply the quation by 3 so that we can eliminate y

3(3x+y=2)=3×2

9x+3y=6

Adding it with 5x−3y=8

9x+3y+5x−3y=6+8

14x=14

x=1

Putting the value of x in equation 3x+y=2

3×1+y=2

3+y=2

y=2−3

y=−1

So, we have x=1andy=−1
