Question

1. Simplify: (3x + 4y – 2z) - (-2z + 6y)

Answer 1

Answer: 3x +10y

Explanation:

first you put all the common integers (i think that is what they are called) together

3x+4y+6y-2z-(-2z)

Then you add and subtract all the integers

4y+6y=10y

-2z-(-2z)=0

so the answer is

3x+ 10y

Hopefully this is the right answer

God bless you!!

Answer 2

Answer: x - 2y + 2z

keep it in alphabetical order!

Explanation:

the negative on the outside changes what is on the inside, so the new equation will be

3x + 4y - 2x + 2z - 6y

combine like terms

x - 2y + 2z
