Question

2х + y = 13
5x - Зу = 16
solve it using substitution​

Answer 1

Answer:

here y=13-2x

so from 2nd equation

5x-3(13-2x)=16

5x-39-+6x=16

11x=55

X=5

and y=13-10=3

Answer 2

Answer:

2x + y = 13...i

5x - 3y = 16...ii

From i,

y= 13 - 2x...iii

Put y = 13 - 2x in equation ii

5y - 3y = 16

5x - 3(13-2x) = 16

5x - 39 + 6x = 16

5x+6x = 16+39

11x = 55

x = 55/11

x = 5

Put x= 5 in equation iii

y = 13-2x

y= 13-2×5

y= 13 - 10

y = 3

x = 5 and y = 3

I hope this helps you.
