X + y = 2

liraira [26]

Answer:

$D. (3,-1)$

Step-by-step explanation:

$x + y = 2 \: \: \: \: \: \: ..(1) \\ 2x - y = 7 \: \: \: \: ..(2)$

from equation 1 we get,

$x = 2 - y$

now,

$put \: \: \: \: x = 2 - y \: \: \: in \: (2)$

we get,

$2(2 - y) - y = 7 \\ 4 - 2y - y = 7 \\ 4 - 3y = 7 \\ - 3y = 7 - 4 \\ - 3y = 3 \\ \\ y = \frac{3}{( - 3)} \\ \\ y = - 1$

now,

$put \: \: \: \: y = - 1 \: \: \: \: in \: (1)$

we get,

$x + ( - 1) = 2 \\ x - 1 = 2 \\ x = 2 + 1 \\ x = 3$

hence, the value of x = 3 and y = (-1)

Answer:

x = 17

Step-by-step explanation:

∠ DCE = ∠ ACE ( vertically opposite angles )

The sum of the 3 angles in a triangle = 180° , then

∠ DCE = 180° - (100 +x) = 180 - 100 - x = 80 - x

∠ ACE = 180 - (49 + 4x) = 180 - 49 - 4x = 131 - 4x

Equating the 2 angles

80 - x = 131 - 4x ( add 4x to both sides )

80 + 3x = 131 ( subtract 80 from both sides )

3x = 51 ( divide both sides by 3 )

x = 17
