Can someone help me solve these

m1=(3x+20)

m3=5x-16

(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

a.) m3 = (5x - 16) (Substitution)

b.) -2x + 20 = m1 -5x (Subtraction Prop. of Equality)

c.) -2x = m1 -5x -20 (Subtraction Prop. of Equality)

d.) x = (m1-20)/3 (Division Prop. of Equality
