Iwant the answer of these questions

1) y=2 and 5x - y = 93

Plug y =2 in second equation

5x-2 = 93

add 2 to both sides

5x = 95

divide both sides by 5

x = 19

So a= 19

Answer 19

2) y = 2x and 5x - y = 93

Again plug in the same way

5x - 2x = 93

3x = 93

divide both sides by 3

x= 31

So a = 31

and b= y = 2x = 2(31) = 62

Answer 62

3)x-3y=1 and 2x+15y = 10

from first equation x= 3y+1

So plug this in second equation

2(3y+1) +15y=10

6y+2 +15y = 10

21y +2 = 10

So k= 21

Answer 21
