Solve: 2x+p/q = 2x+q/p If p=q, if p cannot equal to q

p= -q

Step-by-step explanation:

(2xq+p)/q= (2xp+q)/p

After cross multiplying,

2xpq+p²= 2xpq+q²

p²=q²

p²-q²=0

(p+q)(p-q)=0

either p+q=0 : p= -q

or p-q=0 : p=q which is not possible because of the given condition

Thus, the only solution of this equation is:

p= -q

answer4 to the second power is 16

and 4 to the third power is 64,
