What is the answer to

[x+3y=5

[2x-y=-4

x + 3y = 5 = > x = 5 - 3y

2x - y = - 4

Subs x

2. (5 - 3y) - y = - 4

10 - 6y - y = - 4

10 - 7y = - 4

10 + 4 = 7y

y = 14/7

y = 2

Subs y

2x - y = - 4

2x - 2 = - 4

2x = - 4 + 2

2x = - 2

x = - 2/2

x = - 1

y=2

x=-1

Step-by-step explanation:

2x-y = - 4 (1)

x+3y=5 (2)

x-4y=-9 (move the 4 to rhs)

x=4y-9

sub the x equation into (2)

4y-9+3y=5

7y=14

y=2

sub y into equation (1)

2x-2=-4

2x=-2

x=-1
