h-23=63
Step-by-step explanation:
We must translate this sentence into an equation.
Helena's age decreased by 23 is 63.
The words decreased by tell us to subtract.
In particular, Helena's age decreased by 23 means −h23.
The word is means equals.
So we get the following.
h-23=63
If x = 16 and y = -16, then x+y = 16+(-16) = 0
Alternatively, if x = -16 and y = 16, then x+y = -16+16 = 0
So y = -x and x can be equal to either 16 or -16
