-30.25 - 25 - 1.47x = 3.8(3.3x + 3.1)
Combine like terms on the left side. Distribute the 3.8 on the right side.
-55.25 - 1.47x = 12.54x + 11.78
Add 55.25 to both sides. Subtract 12.54x from both sides.
-14.01x = 67.03
Divide both sides by -14.01.
x = -67.03/14.01 (exact answer)
x = -4.784 (approximate answer)
