Question

5x+36y=21,25*(x+1)=6y ​

Answer 1

Answer:

1.5x + 3.6y=2.1

let multiply 10 on both sides

15x +36y =21

dividing throughout by 3

5x +12y=7----(1)

2.5 (x+1)=6y

multiplying both sides by 10

25x +25=60y

y=25x+25/60-----(2)

(2) in (1)

5x + 12 ( 25x+25/60)=7

5x + ( 25x+25/5)=7

25x+25x+25=7×5

50x +25=35

50x=10

x= 1/5

y=25 × 1/5 +25/60

=5+25/60

= 30/60

=1/2
