2 2/5 - 5y = 2.4 + 1/2 y
Changing the mixed number to a decimal
2 2/5 = 2 4/10 = 2.4
2.4 - 5y = 2.4 + 1/2y
Changing the fraction to a decimal
1/2 = 5/10 = .5
2.4 - 5y = 2.4 + .5y
Subtract 2.4 from each side
2.4 -5y - 2.4 = 2.4 + .5y - 2.4
-5y =.5y
Subtract .5y from each side
-5y - .5y = .5y - .5y
-5.5y = 0
Divide by -5.5
-5.5y/-5.5 = 0/-5.5
y = 0
