## anonymous 5 years ago simplify 10x - (3x - (7x + 2))

1. anonymous

Start inside the parenthesis: 10x - (3x - 7x - 2)

2. anonymous

then distribute again and get: 10x - 3x + 7x + 2

3. anonymous

Combine like terms: 14x + 2

4. anonymous

could you help me with a second one like that

5. anonymous

sure

6. anonymous

(4/5x)/(-2/15x)

7. anonymous

to divide fractions, you have to multiply by the reciprocal of the second fraction:

8. anonymous

9. anonymous

$\frac{4}{5x} * \frac{15x}{-2}$

10. anonymous

the x's would cancel, so the answer is just -6

11. anonymous

makes sense
