Answer:

#3y + 5 >= 5x - 12#

Explanation:

"3y plus 5": Plus is the same as #+# so this can be written as:

#3y + 5#

"5x minus 12": Minus is the same as #-# so this can be written as:

#5x - 12#

"is at least" This means it as equal to or greater than so this can be written as:

#>=#

Putting these all together gives:

#3y + 5 >= 5x - 12#
