#### Answer

x = 0

#### Work Step by Step

0.5(x + 2) = 0.1 + 3(0.1x + 0.3)
Expand the left side of the equation:
0.5(x + 2) = 0.5x + 1
Expand 3(0.1x + 0.3) = 0.3x + 0.9
Rewrite the equation:
0.5x + 1= 0.1 +0.3x + 0.9
Subtract 1 from both sides:
0.5x + 1 -1 = 0.1 +0.3x + 0.9 - 1
0.5x = 0.3x
0.5x - 0.3x = 0.3x - 0.3x
0.2x = 0
Divide both sides by 0.2:
x = 0
