Question

Whats x for both of these equations

Answer 1

x = (-1)

y = 3

Explanation:

y = -2x + 1

y = x + 4

2x + y = 1 _______(1)

-x + y = 4_______(2)

`- x + y - (2x + y) = 4 - 1 \\ - x + y - 2x - y = 3 \\ - 3x = 3 \\ x = (3)/( - 3) \\ x = - (1) \\`

x = (-1),

`2x + y = 1 \\ 2( - 1) + y = 1 \\ - 2 + y = 1 \\ y = 1 + 2 \\ y = 3 \\`
