Answer:

#x = - 1 #

Explanation:

#13x - 4 ( 2x - 5) = 15#

#13x + (- 4) * ( 2x) + (-4) * ( - 5) = 15#

#13x -8x + 20 = 15#

#5x + 20 = 15#

#5x = 15 - 20 #

#5x = - 5 #

#x = - 5 /5 #

#x = - 1 #

Answer:

#x=-1#

Explanation:

We can start by distributing the #-4# on the left side to get

#13x-8x+20=15#

We can simplify the #x# terms on the right to get

#5x+20=15#

Next, to further isolate the #x# term, we can subtract #20# from both sides. We now have

#5x=-5#

Our last step would be to divide both sides by #5#. We get

#x=-1#

Hope this helps!
