Hi,
AxB = 0 means A=0. or B=0
so 2 solutions :
4x-3= 0
4x=3
x = 3/4
and x+2 = 0.
x= -2
solutions are : -2 +and 3/4
The table you drew under the question is exactly the right way to start.
-- Make a second column, next to the 6 and 7. This column will be
the actual number of each thing.
-- You know that there are 42 marbles, so write '42' in the box
next to the 6, on the 'Marbles' line.
Now you need to figure out what to write in the 'Stones' line, next to the 7.
-- Look at the 'Marbles' line. There's a 6 and then a 42.
Ask yourself: " Self ! What does the 6 have to be multiplied with to get 42 ?"
-- Whatever the answer is, drop down to the 'Stones' line,
and multiply the 7 by the same number.
The product is the total number of stones, and it goes in the box.

(The mystery number is 7. There are 49 stones.)

Answer:
x≤3
Step-by-step explanation:
<em>Step one- This equation has 23 greater than or equal to sign. Which means It can be at most 23</em>
<em>Step two- Find out what times 3x+14=23 In this case the answer is 3.3 Is the biggest number that can be multiplied by 3, +14 to get to 23.</em>
<em>Step three- Rewrite the Answer. Since we know that 3 is the highest numebr possible, we rewrite it to this equation</em>
<h3>x≤3</h3><h3>HOPE THIS HELPS :)</h3>
