Answer:
x=2.1
Step-by-step explanation:
collect like terms 2.4x+5.8x=8.2x
move the terms to the left side and change its sign to -8.2x
move the constant(-3.28) to the right and change its sign to 3.28
equation should now be 9x-8.2x=-1.6+3.28
next you're going to do 9x-8.2x=0.8x
then -1.6+3.28=1.68
divide both sides of the equation by 0.8
x=2.1 is your final answer
