Final answer:
To write the sentence as an equation, use 122 + y = 113 and solve for y.
Step-by-step explanation:
The sentence can be written as the equation 122 + y = 113. In this equation, 122 represents the value you have, y represents the unknown quantity, and 113 represents the sum you need to achieve. To find the value of y, you can subtract 122 from both sides of the equation:
122 + y - 122 = 113 - 122
This simplifies to y = -9, meaning that y is equal to -9.
