the sum of a number and 32 is 43

Question

write a equation using n for the variable for this equation.solve

Answer 1

in math specific word has a meaning . when you say sum of two numbers , then you think of adding 1+3 . Since we don't know those numbers we call them x and y , so for saying the sum of two numbers is 10 , you would translate it as x+y = 10 .

In your case the sentence says .. the sum of a number ( I don't know the number - let's call it x ) and 32 is ( in math this means equal ) 43.

then to translate it in math expression x+32=43. ( equation )

Then you have to find the number ( x ) . in order to do that you need to find the number that added to 32 = 43. Therefore you substract 32 from 43 since you added to get to 43.

x = 9

how do you check .. is 9+32 = 43 ( true )
