I would go with option C. x, in the first equation.
The X term has a coefficient of 3, the lowest common factor amongst the 3 terms making for easy isolation of the variable.
Answer:
We must prove that (c+a)(c+d) = (b+c)(b+d)
- Let us use principles from mathematical induction

- a=bx , b=cx, c=dx
- a+c = b + c
- c +d = b + d
- Such that (a+c)(c+d)=(b+c)(b+d)
Rate positively and give brainlist
