Answer:
x=0.159
Step-by-step explanation:
Let's start with multiplying both sides by 7 to remove the division bar.
4x-3=2.87-14x
Add 14x to both sides so there's only one x.
18x-3=2.87
Add 3 to both sides to remove the 3 from the x.
18x=2.87
Divide both sides by 18 to remove the 18 from the x.
x=0.159
