Question

The sum of two numbers is 77. The greater number is 5 more than the smaller number. Which equation can be used to solve for the smaller number?

Answer 1

x(x − 5) = 77
x(x + 5) = 77
x − (x + 5) = 77
x + (x + 5) = 77

Answer 2

X + x + 5 = 75

Answer 3

Wait I meant 77

Answer 4

So d

Answer 5

its D

Answer 6

D is good

Answer 7

always try to think in algebraic way.
when the say the number (not saying what is )
give it a name x or whatever letter denoting that it is what we are looking for
so we have in this case two number
if said the small number is x
and we know the greater is 5 more than the small
we are essentially saying x+5
and the sum of the two x+(x+5)=77

Answer 8

it is a matter of reading and translating the meaning of a words within the problem
