4x+2y=-24 -4x+y = 12

allsm [11]

Answer:

Step-by-step explanation:

4x+2y = -24 -------------(i)

-4x+y = 12 -------------(ii)

add (i) &(ii) 3y = -12

y = -12/3

y = -4

Put y = (-4) in (i)

4x + 2*(-4) = -24

4x - 8 = -24

4x = -24 + 8

4x = -16

x = -16/4

x = -4

Solve both! For x |X + 2| > 5 |X + 2| < 5

NISA [10]

Answer:

Your Answer is ...

x > 3 or x < -7

Step-by-step explanation:

1. x > 3 worked out

|X + 2| > 5

Solve absolute Value

|X + 2| > 5

We know either |X + 2| > 5 or x + 2 < - 5

_________________________________

$x + 2 > 5\\x + 2 - 2 > 5 - 2 (Subtract ~2~ from~Both~sides)\\ x >3$

2. x < -7 Worked out

$x + 2 < - 5\\x+2-2>5-2 (Subtract~2~from~Both~sides)\\x$

Hope this Helps!

Take Care!
