Question

Please give me the answer for x + 4 equals 7

Answer 1

x+4=7
So subtract 4 from both sides which means to put minus four under the four and seven.For example x+4=7
-4 -4
Then cross out the two fours.
Afterwards do 7-4
Which gives you 3
So 3 is your number.

Answer 2

x = a number
x = 3


x + 4 ? = 7 , 7 - 4 = 3

x = 3 , 4 + 3 = 7

x = 3

i hope this helps
