-5 + x
(n + 5)/2
The expression which represents half the sum of five and a number b is (b+5)/2.
the quotient of 12 and a number h
5x+17
The appropriate equation is: 5*(-3 + N) = -20
1.6
1/2x=-5
Half of 18 is 9 and 5+4 = 9 so the number is 5
x/2 + 5
3Y - 2 = X + 5 This presumes "a number" and "x" are two separate values. If they are the same number, the equation would be 3X - 2 = X + 5. In this equation, X = 3.5.
