Let's solve your inequality step-by-step. 3(−2−x)+x>20

Step 1: Simplify both sides of the inequality. 4x+6>20

Step 2: Subtract 6 from both sides. 4x+6−6>20−64x>14

Step 3: Divide both sides by 4.4x4>144

x>7/2

x > 3.5 

-3(-2 - x) + x > 20 
6 + 3x + x > 20 
6 + 4x > 20
-6          -6
4x > 14
/4      /4
x > 3.5
