If 5x-4+13=5 , then x=1/2

Answer 1

we have that
If (5x-4+13x=5) --------------> then x=1/2
Step 1
let's substitute the value of x = (1/2) in the expression [5x-4+13x] and verify its result
5*(1/2)-4+13*(1/2)
(5/2)-4+(13/2)
(5-4*2+13)/2----------> (5-8+13)/2=10/2=5
then
5=5-----------> the value of x = (1/2) satisfies equality
