Step 1: Simplify both sides of the equation.
− 2 ( x + 4.1 )
= x + 2 x + 12.3 ( − 2 ) ( x ) + ( − 2 ) ( 4.1 )
= x + 2 x + 12.3
(Distribute)
− 2 x + − 8.2 = x + 2 x + 12.3 − 2 x − 8.2
= ( x + 2 x ) + ( 12.3 )
(Combine Like Terms)
− 2 x − 8.2 = 3 x + 12.3 − 2 x − 8.2
= 3 x + 12.3
Step 2: Subtract 3x from both sides.
− 2 x − 8.2 − 3 x
= 3 x + 12.3 − 3 x − 5 x − 8.2
= 12.3
Step 3: Add 8.2 to both sides.
− 5 x − 8.2 + 8.2
= 12.3 + 8.2 − 5 x = 20.5
Step 4: Divide both sides by -5.
− 5 x − 5 = 20.5 − 5 x = − 4.1
