The sum of 4 times a number and 5 equals 7 .

Answer 1

Hey! Lets solve this shall we ?

So, we must translate this equation from words into a mathematical equation

4x + 5 = 7 .......................First we subtract 5 to both sides such that

4x = 2...................Then divide 4 to both sides to get

x = (2/4) = 1/2

I hope this helped!
