Complete the solution of the equation. Find the value of y when x equals -14. -2x + 5y = 8

shepuryov [24]

Answer:

y = -4

Step-by-step explanation:

-2x + 5y = 8

Let x=-14

-2(-14) +5y = 8

28 +5y = 8

Subtract 28 from each side

28-28 +5y = 8-28

5y = -20

Divide by 5

5y/5 = -20/5

y = -4

Given: y = -x - 6

arlik [135]

$y=\dfrac{-x-6}{2}\qquad\text{multiply both sides by 2}\\\\2y=-x-6\qquad\text{subtract 2y from both sides}\\\\0=-x-2y-6\\\\\boxed{-x-2y-6=0}\qquad\text{change the signs}\\\\\boxed{x+2y+6=0}$
