   ➵ab=2(a+b)+2a

   ➵Step 1: Add -4a to both sides

   ➵ab+−4a=4a+2b+−4a

   ➵ab−4a=2b

   ➵Step 2: Factor out variable a.

   ➵a(b−4)=2b

   ➵Step 3: Divide both sides by b-4.

   ➵a(b−4)b−4=2bb−4a=2a

   ➵Answer :a=2b b−4

   [tex]➵ANSWER:-[/tex]

   = 3*x = 2(3+x)+(2×3)=4

   = 6+2x+6=4

   12+2x = 4

   2x = 4-12 = -8

   x =

   [tex] \frac{ – 8}{2} = – 4[/tex]
