18/6=3
Answer:
x+y+3 or 1x+1y+3
Step-by-step explanation:
3/4x+1/4x+1y+3
3/4x+1/4x=1x
1x+1y+3
You can't do x+y+3 so it stays x+y+3. Hope this helps.
Answer:
{-14, 4}
Step-by-step explanation:
the absolute value function only makes sure that the result always has a positive sign.
so, (x + 5) must be either +9 or -9 to make the original equation true. the absolute value would turn both into +9.
so,
x + 5 = 9
x = 4
and
x + 5 = -9
x = -14
that gives us the correct set of solutions as indicated above.

Answer:
Step-by-step explanation:
At first sight this equation has 3 terms. Multiply all 3 of them by 10 to remove the fractions:
4b + 13 = 4(b - 5)
Carrying out the multiplication, we get:
4b + 13 = 4b - 20
This can never be true (13 is never equal to -20), so this equation has NO SOLUTION.
