1.	A number P is aivide byThe sum of a number x and twice the number y is 30.
Answer» the first number = x the second number = y The sum of two numbers is 30. x + y = 30 The first number is twice the second number. x = 2y substitute 2y in for x in the first equation x+ y = 30 2y+ y = 30 3y = 30 y = 30/3 y = 10 then put 10 in for y x = 2*(10) x =20

A number P is aivide byThe sum of a number x and twice the number y is 30.

Answer»

the first number = x

the second number = y

The sum of two numbers is 30.

x + y = 30

The first number is twice the second number.

x = 2y

substitute 2y in for x in the first equation

x+ y = 30

2y+ y = 30

3y = 30

y = 30/3

y = 10

then put 10 in for y

x = 2*(10)

x =20
