Answer: 7 pupils</h3>
======================================================
Explanation:
p = number of pupils
If each student gets 6 marbles, then that accounts for 6p marbles so far. Unfortunately in this situation, we're short 12 marbles. That means we really have 6p-12 marbles.
On the other hand, if each student gets 4 marbles each, then that's 4p marbles so far. Then we add on 2 since we have a those extra. In this situation we have 4p+2 marbles.
The expressions 6p-12 and 4p+2 represent the same total marble count. Set them equal to one another and solve for p.
6p-12 = 4p+2
6p-4p = 2+12
2p = 14
p = 14/2
p = 7 is the number of pupils
-------------
Optional Section:
If you want to know the number of marbles, then say either
6p-12 = 6*7-12 = 42-12 = 30
or
4p+2 = 4*7+2 = 28+2 = 30
Either way, we have 30 marbles.

Answer: The answer would be x < 10/7
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
7*x (10)>0
Step by step solution :
STEP
1
:
Pulling out like terms
1.1 Pull out like factors :
7x - 10 = -1 • (7x + 10)
Equation at the end of step
1
:
STEP 2
:
2.1 Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
7x+10 < 0
2.2 Divide both sides by 7
x+(10/7) < 0
Solve Basic Inequality :
2.3 Subtract 10/7 from both sides
x < 10/7
Inequality Plot :
2.4 Inequality plot for
7.000 x - 10.000 > 0
One solution was found :
x < 10/7
