Question

Simultaneous eqt..
Зу = х - 2
2х + 5y = 15
substitution method
​

Answer 1

Answer:

Зу = х - 2

2х + 5y = 15

x-3y=2...(1)×2

2x-6y=4...(2)

2x+5y=15...(3)

subtract 2 from 3

2x+5y=15

- 2x-6y=4

__________

11y=11

y=11/11

y=1

substitute y=1 in equation (1)

x-3y=2

x-3(1)=2

x=2+3

x=5
