$x = 24$ $x=24$

First of all subtract 19 from 39

$39 - 19 = 20$ $39-19=20$

then isolate $x$ $x$ and rearrange the equation

$20 + 4 = x$ $20+4=x$
remember when you bring 4 to the other side the sign changes.

Here it was $- 4$ $-4$ which you change to $+ 4$ $+4$

finally you add both the numbers $20 + 4 = 24$ $20+4=24$

hence $x = 24$ $x=24$
