Question

x + 4y = - 4, x + 2y = 8
please solve the above equation by Elimination method ​

Answer 1

Step-by-step explanation:

x +4y = -4

x + 2y = 8

2y = 12

y = 6

put y = 6 in equation ( 1)

x + 4 × 6 = - 4

x+ 24 = -4

x = -4 - 24

x = 28

Answer 2

Answer:

x = 20

y = -6

Step-by-step explanation:

x +4y = -4

x +2y = 8

_. _. = _( the signs will change)

2y = -12

=> y = -6

therefore fir finding x:-

x+ 4*-6= -4

x -24= -4

x = -4+24

x. = 20
