-5-2%283x-4%29=21 Start with the given equation



-5-6x%2B8=21 Distribute


-6x%2B3=21 Combine like terms on the left side


-6x=21-3Subtract 3 from both sides


-6x=18 Combine like terms on the right side


x=%2818%29%2F%28-6%29 Divide both sides by -6 to isolate x



x=-3 Divide

--------------------------------------------------------------
Answer:
So our answer is x=-3

-5+-+2%283x+-+4%29+=+21+....move -5 to the right

+-+2%283x+-+4%29+=+21+%2B+5+
+-+2%283x+-+4%29+=+26+.....divide both sides by -2
+-+2%283x+-+4%29%2F-2+=+26%2F-2+.....
+3x+-+4+=+-13+.....move -4 to the right
+3x++=+-13%2B+4+.....
+3x++=+-9+..... divide both sides by 3
3x%2F3+=+-9%2F3
x+=+-3
