Answer 1

Answer:

4. so we have:

n + n+1 + n+2 = 48.

simplified, it looks like:

3n + 3 = 48

Subtract 3 from both sides, and we have:

3n = 45

Divide both sides by three to isolate n and we have:

n = 15

so our numbers should be 15, 16, and 17.

Checking out answer, we get that:

15 + 16 + 17 = 48

5. .x+(x+2)+(x+4)=96

3x+6=96

3x=90

x=30, x+2=32, x+4=34 (answer)

without algebra...

96/3=32, 32-2=30 and 32+2=34

6. 3x-5=1

3x-5 =1

+5 =+5.....add

========

3x=6

3x/3=6/3...divide both sides by 3

x=2

to check, substitute 2 for x in equation

3(2)-5=1

6-5=1

1=1....correct
