5 < 4x = 2> 3x PLEASE HELP

Looks fishy to me, the way this problem combines <, = and > symbols.

But anyway.  Subtract 3x from both sides.  You'll get

5 < x = 2 > 0      2 > 0 is true, but that's a different type of math problem (true or false).    If you decide to substitute '1' for 2 > 0, then the "1" says "TRUE."

Then 5 < x = true, so you must find x values that are larger than 5.

That would be (5, infinity)

Please go back and ensure that you have copied down the original problem exactly as it appears.

elena-14-01-66 [18.8K]

Answer:

9/5

Step-by-step explanation:

The common difference = 6 - 2 = 4

The age after 6 is 6 + 4 = 10 = y

The age after 14 is 14 + 4 = 18 = z

z/ y = 18/10 = 9/5

What is the solution of the system? Use elimination. 7x + 5y = 19 −7x − 2y = −16
netineya [11]

Make the coefficient of y the same in both equations:

To do this, multiply equation one by 2, and equation two by 5 (this will make the coefficient 10 in both).

14x + 10y = 38
-35x - 10y = -80


Eliminate the y variable by adding the equations from each other

   (14x + 10y = 38)
+ (-35x - 10y = -80)
=  -21x +  0y  = -42

We now have -21x = -42. The y variable has been eliminated.


Solve for x

-21x = -42

Divide both sides by -21 to get x on its own.

x = 2


Substitute x into the equation to find y.

7*2+5y=19

14+5y=19

Subtract 14 from both sides.

5y=19-14

5y=5

Divide by 5 on both sides to get y on its own.

y=5/5

y=1


The answer is (2,1)
