In a question like: 3 − (2x − 5) < −4(x + 2)

1 answer:

4 0

Answer:

Step-by-step explanation: I think -5 would change to a positive 5 because of the distributive property. In the part -(2x-5), there is a invisible 1 next to the left parenthesis, so it would be -1(2x-5). Then you would distribute the -1 one to the 2x and the -5. So the thing would look like this: -2x+5.

|a+3|/2=1

|a+3|=1*2

|a+3|=2

a=2-3

so,a=-1

second

2|b+1|=6

|b+1|=6/2

|b+1|=3

b=3-1

so,b=2

now,|a+b|

= -1+2

= 1

therefore,|a+b|= 1
