Question

I dunno how to solve these so I need some help

1. x-9x

2. -6x - x

3. -9x + 9x

4. -60x + 62x

Answer 1

Easy.

x - 9x = -8x

-6x - x = -7x

-9x + 9x = 0

-60x + 62x = 2x

Answer 2

1) x-9x=-8x

2) -6x-x=-7x

3) -9x+9x=0

4) -60x+62x=2x

I hope this can be useful

Answer 3

1) x - 9x = -8x

2) -6x - x = -7x

3) -9x + 9x = 0

4) -60x + 62x = 2x

Answer 4

1. x-9x = -8x

2. -6x - x = -5x

3. -9x + 9x = 0

4. -60x + 62x = 2x

Note:

Rules for Addition:

Positive + Positive = Positive

Positive + Negative = (copy the sign of the bigger amount)

Negative + Negative Negative

When subtracting integers:

First, change the SUBTRACTION problem to an ADDITION problem;

Then, follow the rules (above) for solving the new ADDITION problem.

Positive + Positive = Positive

Positive + Negative = (copy the sign of the bigger amount)

Answer 5

1. x-9x = -8x

2. -6x-x = -7x

3. -9x + 9x = 0

4. -60x+62x = 2x  

Answer 6

1. x-9x = -8x

2. -6x-x = x(-6-1)=x(-7) = -7x

3. -9x+9x = x(-9+9) = x(0) = 0

4. -60x+62x = x(-60+62) = x(2) = 2x

these are the answers
