Respuesta :
Answer:7.5
Step-by-step explanation:
move all unknowns to one side by either adding or subtracting from both sides
so, subtract 4x from both sides and you get 2x-10=5
now mode -10 to the other side by adding 10 to both sides. you get 2x=15
divide both sides by 2 to get x by itself
you get x=7.5
