the sum of two numbers is 18. the sum of the grates number and twice the smaller number is 25. find the nubers. write the two equtions and find both numbers

Answer 1

Try writing both equations down. X+y=18 and x+2y=25. X represents number #1 and y represents the second number (on the second equation it is multiplying by two because it says that the greater number and twice the smaller number is 25).

try solving the second equation until you get the answer of x. The answer will have y in it. Incorporate that answer on the first equation. Put the answer of the second equation instead of X.

solve the equation and it should give you the answer for y. Hint... it should be 7 ;) Then, replace Y with the number you obtained and you will get the answer for X.

If this is not clear. I could try explaining in in a different way.
