Question

b) Determine the value of x if 15 and 3−8 are equivalent:
i) 20 ii) -20 iii) 40 iv) -40

Answer 1

Answer:

Umm.. that's a wrong question. How I am gonna determine the value of X, if you don't include X in the equation.?

Answer 2

Answer:

Equivalent means equal -

x(15) = x(3-8)

15x= 3x-8x

15x= -5x

15x +5x = 20x

x = 20

Thus answer is 20
