Question

10x + y = -3 and y =-1 , find x​

Answer 1

Answer:

∴ x = -1/5

Step-by-step explanation:

given,

 10x + y = -3

y = -1

here,

  10x+ y = -3

or, 10x + (-1) = -3

or, 10x  - 1 = -3

or, 10x = -3 + 1

or, 10x = -2

or, x = -2 / 10

∴ x = -1/5

Answer 2

Given that,

10x + y = -3

y =-1

Now,

10x + (-1) = -3

10x -1 = -3

10x = -3+1

10x = 2

x = 2/-10 = 1/-5

∴x=1/-5
