Answer
Given,
proton represent positive charge
the integer that will give the representation of 5 protons will be equal to + 5
an electron represents negative charge
the integer that will give the representation of 3 electrons will be equal to -3
y = 4
first note that the right side simplifies to 12, equation can be written
= 12 ( multiply both sides by 0.8 )
2y + 1.6 = 9.6 ( subtract 1.6 from both sides )
2y = 8 ( divide both sides by 2 )
y = 4
Answer:
2x-y-13=0
