Question

solve
5x-3y=8,3x+y=2,then what are the values of x and y?​

Answer 1

Answer:

Step-by-step explanation:

5x+3y=8

3x+y=2. × 3

= 5x+3y=8

9x+3y=6

_. _. _

____________

-4x=2

=x=. -2

___

4

then, y =5×(-2/4)+3y=8

y=....

Answer 2

Answer:

Step-by-step explanation:

1. first of all you have to know that we first use one of the letters x and y
2. I will find y first using the second equation
3. 3x +y=2 giving us y=2-3x
4. now since we know y=2-3x we are going to find x using the fisrt equation
5. 5x-3y=8 giving us 7/4
6. so using x=7/4 we can workout y to get the exact answer
7. y=2-3x replacing x with 7/4 we get y=2-3[7/4] which will = 1
8. therefore y=1 and x=7/4
