( -\frac{x}{7} )+ 4 - 3(x) \ \textgreater \  0
Solve this: \frac{x}{7}
Take the '0' from behind the equal sign in the first step
0 -  \frac{x}{7} + 4 - 3x \ \textgreater \  ?
\frac{-4(7)}{7}
-7(4) = 28 - x
\frac{28 - x}{7} - 3(x0 \ \textgreater \ ?
\frac{3(x)}{7}
Your inequality plot would be: -3.143 (4.0) \ \textless \  0
We have One Solution in this problem
Your answer would be: x\ \textless \  \frac{14}{11}  if we added \frac{14}{11} both sides of the inequality plot 

Side Note: You don't have to do this method to solve inequalities, you can do whatever helps you out more 

So, you're correct with your answer as C.

\dfrac{-x}{7}+4\geq3x\\
-x+28\geq21x\\
22x\leq28\\
x\leq\dfrac{28}{22}\\
x\leq\dfrac{14}{11}

Solve for x:<br> 3(x+1)=5 (x-2)+7
Aleonysh [2.5K]

Step-by-step explanation:

3( x +1) = 5 (x - 2) + 7

3x + 3 = 5x - 10 + 7

5x - 3x = 3 + 10 - 7

2x = 13 - 7

2x = 6

Therefore x = 3
