Answer:
7+(x+5) (original equation)
x+12 (simplified)
Explanation:
So we know the number is x
Since its just an expression we can’t make x equal to anything so the best we can do is simplify the expression given.
so 7 plus the sum of x and 5
7+(X+5)
Mow just simplify it
x+5 is x+5
x+5+7 is 12+x becuase 5+7 is 12 and I combined like terms
x+12
