Question

if 3 is added to twice a number, the result is the difference of 4 times the number the number and 5.

Answer 1

Let, the number = x

Then, 2x + 3 = 4x - 5

2x - 4x = -5 - 3

-2x = -8

x = 8/2

x = 4

In short, the number would be: 4

Hope this helps!

Answer 2

2n+3=4n-5  subtract 4n from both sides

-2n+3=-5  subtract 3 from both sides

-2n=-8  divide both sides by -2

n=4
