Answer: 3.65

Step-by-step explanation:

This question is asking basically what is 50% or 1/2 of 7.3.

PLZ HELP ME &gt;&gt;&gt;&gt;&gt;&gt;THANKYOU
Aleonysh [2.5K]

Step-by-step explanation:

There are two commonly recognized beginner methods to solve a system of equations.  The first is elimination and the second is substitution.  I will go over both of them here.

Substitution:

y=-2x-9, y=-5x-21

-2x-9 = -5x -21

3x=-12

x=-4

y=-5(-4)-21

y=-1

Elimination:

This method is a bit hard to explain without visual aid, but I'll try my best :)

In elimination you can subtract each value with a common variable from its counterpart in the other equation.  For this example, subtract y-y to get 0, -2x - (-5x) to get 3x, and -9 - (-21) to get 12.

Thus,

-12=3x

x=-4

y=-5(-4)-21

y=-1

Hope it helps and lmk if you need more help <3 :D
