Combine like terms. First, add 4.2x to both sides. This results in 1.8+0.5x = 0.3, and then 0.5x = 0.3-1.8.
Next, 0.05x = -1.5, or 5x = -150, and x = -30.
Must check this result by substitution of -30 for x in the original equation.
Is 1.8-3.7(-30)=-4.2(-30)+0.3 true or false?

A store advertises 15% off an item that regularly sells $300. How is a 15% discount similar to a 15% decrease? Explain.
Kobotan [32]
Both a discount and decrease will make the cost the same which is $225 for the object. I think that's what your asking. I'm sorry if it is not that helpful.
