Step-by-step explanation:
The answer is 25 and make sure it’s correct
<span>5(x – 4) + 3x – 9x = 6 – (2x + 5) + 8x
step1:- 5x - 20 + 3x - 9x = 6 - 2x - 5 + 8x
step2:- 5x + 3x - 9x - 20 = 8x - 2x + 6 - 5
-x - 20 = 6x + 1
stp 3
-20 = 7x + 1
step 4
-21 = 7x
divide both sides by 7:-
-3 = x
thats the solution x = -3
