Question

- Substitution method:
ii) 5x – y += 0 & 10x - 2y + 15 = 0
iii) 3x + y -14 = 0 & 2x + 5y -5 =0​

Answer 1

Answer:

2 ans

Step-by-step explanation:

2(3x+y-14-0)

3(2x+5y-5-0)

6x+2y-28-0

6x+5y-15-0

- - + +

-13y-13-0

-y is equal to -1

then,

2x+5y-5=0

2x+5.-1-5=0

2x-5=5

2x=5+5

2x=10

x=5
