PLZ EXPLAIN!!!Fill in the missing information in this Algebraic proof. Please label your answers as a, b, c, ... (Vertical Angles are Congruent) a.) _____ = (5x - 16) (Substitution) b.) -2x + 20 = _____ (Subtraction Prop. of Equality) c.) -2x = _____ (Subtraction Prop. of Equality) d.) x = _____ (Division Prop. of Equality
Since vertical angles are congruent, you can equate them, so u get 3x+20 = 5x-16 did u get the a) part ?
kind of is that how i fill out the a part?
yes. now for b) part u subtract 5x from both sides, u get -2x+20 = -16
now subtracting 20 from both sides, we get -2x=-16-20 -2x=-36
that was c) part -2x=-36 now d) part dividing -2 on both sides x= -36/-2 = 18 x=18
