To find the answer to -10x=-210 you must divide -210 by -10
-210/-10= 21
Therefore x=21
So the proper equation is -10(21)=-210

Answer:
AC = 6
Step-by-step explanation:
given ∠A = ∠C then triangle is isosceles with BC = AB, hence
3x - 8 = x + 4 ( subtract x from both sides )
2x - 8 = 4 ( add 8 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
⇒ AC = x = 6
