Answer:
x=2 ; y=-5
Step-by-step explanation:
4 - (x+2) < -3(x+4)
4 -1(x) -1(2) < -3(x) -3(4)
4 - x - 2 < -3x -12
<u> +3x +3x </u>
<u />2 + 2x < -12
<u>-2 -2
</u> 2x < -14
<u /> <u> ÷2 ÷2 </u>
x < -7
assume that x = -8
4 - (-8 + 2) < -3(-8 + 4)
4 - (-6) < -3(-4)
4 + 6 < 12
10 < 12 the inequality is true.
