<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.<br><br> y = 2x + 8<br> 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 )
