Answer:-7x-10y+10z . Explanation: First you have to arrange the number like this : x-y+2z+3x-6y-7x+8z-3y+2x. Then you have to arrange all the x numbers, y numbers and z numbers like this : x+3x-7x+2x-y-6y-3y+ 2z+8z. Then you have to follow the formula:( plus + plus = plus )( minus + minus = plus )( minus + plus = minus )( plus + minus = minus )* In x, y and z which number is greater that number's sign is used. Then you have to add all x numbers like :3x-7x= -4x -4x+2x+x = -7x . Then you have to add all y numbers like : -y-6y-3y = 10y. Then you have to add all z numbers like : 2z + 8z = 10z .So total answer is : -7x-10y+10z . These are the explanation I have written to understand ☝️☝️.
