Answer:
The first step is add 15.9 both sides (addition property of equality)
Step-by-step explanation:
we have
[tex]3.7x-15.9=2.97[/tex]
applying the Addition Property of equality ---> whatever is added to one side of the equal sign must be added to the other side)
Adds 15.9 both side
[tex]3.7x-15.9+15.9=2.97+15.9[/tex]
[tex]3.7x=18.87[/tex]
Applying the Division Property of equality ----> if you divide both sides of an equation by the same nonzero number, the sides remain equal
Divide by 3.7 both sides
[tex]x=18.87/3.7=5.1[/tex]
