If the addition of two. natural numbers is 154 and SUBSTRACTION is 28 so what are the two numbers |
|
Answer» ong>Step-by-step explanation: Let x equal one NUMBER and y the other number. One equation would be the sum of the numbers. x + y = 12
the other equation would be the difference of the two numbers x − y = 4
Now add the two equations x + y = 12
and
x − y = 4
(adding + y and − y = 0 ) so 2 x = 16
Now divide both sides by 2 2 x 2 = 16 2
This gives x = 8 Now substitute x into one of the equations and SOLVE for y 8 + y = 12
subtract 8 from both sides 8 − 8 + y = 12 − 8
This gives y = 4
PUT VALUES into the SECOND equation to check 8 − 4 = 4
4 = 4
check x = 8 and y = 4 helpful to you |
