<h3>Here is your Answer </h3>

$\frac{1}{2} \times - 2 + \frac{1}{3} \times - 5 \\ \\ = \frac{1}{ \cancel2} \times \cancel{- 2} + \frac{1}{3} \times - 5 \\ \\ = 1 \times - 1 + \frac{1}{3} \times - 5 \\ \\ = - 1 + ( - \frac{5}{3} ) \\ \\ = - 1 - \frac{5}{3} \\ \\ = \frac{ - 3 - 5}{3} \\ \\ = \frac{ - 8}{3} = - 2 \frac{2}{3}$

Solve the system of linear equations by substitution. y = 2x + 8 y = -2x

posledela

Answer:

(- 2, 4 )

Step-by-step explanation:

y = 2x + 8 → (1)

y = - 2x → (2)

substitute y = 2x + 8 into (2)

2x + 8 = - 2x ( add 2x to both sides )

4x + 8 = 0 ( subtract 8 from both sides )

4x = - 8 ( divide both sides by 4 )

x = - 2

substitute x = - 2 into (2)

y = - 2(- 2) = 4

solution is (- 2, 4 )
