7+3x≤8(3+x) perform indicated multiplication on right side

7+3x≤24+8x subtract 8x from both sides

7-5x≤24 subtract 7 from both sides

-5x≤17 divide both sides by -5 (and reverse direction of inequality sign because of multiplication/division by a negative value)

x≥-17/5

x≥ -3.4

Step-by-step explanation:

I'm assuming that ED is an exactly straight line, that would mean the angle is 180 degrees. So the sum of the angles in between should also equal 180. This gives you the equation

100 + 20 + x = 180

120 + x = 180

60 = x
