Answer:
The solution to the set of linear equations is:

Step-by-step explanation:
Hey there!
In order to solve this system of equations, we can put the equations equal to each other since both equations are equal to y

Now we simplify
---> 
So now that we know that x is equal to 5, we can find the value of y
let's substitute it in one of the equations
---> 
So now we know that the point where the two equations intersect is:

This is going to be our solution

Hi there...
2( x - 6) < 1/2(12x - 8)
2x - 12 < (12x- 8)/2
2x - 12 < 6x - 4
2x - 6x < -4 + 12
-4x < 8
Divide both sides by -4
-4x/-4 < 8/-4
x > - 2
Question 3. You divide 5 1/4 by 3/4 then multiply that by 20.
The answer is 140
Answer would be -4 5/12
Hope that helps.
