Question

If y=3/5x + 26, find the value of y when x=12

Answer 1

given that, y=3/5x + 26

when x=12

then, y = ( 3/5) × 12 + 26

y = (36/5) + 26

y = (36 + 130) / 5

y = 166 / 5

y = 33.2

Answer 2

y = 3/5x + 26

putting x = 12

y = [ 3/( 5×12) ] + 26

y = 3/60 + 26

y =( 1/ 20) + 26

taking LCM

y = ( 1 + 520)/ 20

y = 521/20
