The value of the number is 57/16
The mathematical statement is given as:
Nine times a number y subtracted from 85 is seven times the sum of four and y
Remove the above mathematical statement as an algebraic expression
85 - 9y = 7(4 + y)
Open the bracket
85 - 9y = 28 + 7y
Collect the like terms
9y + 7y = 85 - 28
Evaluate the like terms
16y = 57
Divide both sides by 16
y = 57/16
Hence, the value of the number is 57/16
