Question

What value of y satisfies the equation 5y+2=4.5?

Answer 1

To solve this, we use the balancing method
What we do to one side, we do the same to the other

5y + 2 = 4.5
      (-2)   (-2)
5y       = 2.5
(/5)         (/5)
y         = 0.5

y = 0.5

Answer 2

5y + 2 = 4.5
       -2    -2


5y = 2.5
5y/5 = 2.5/5

y = 0.5

Answer: y = 0.5
