<span>The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.</span>

We can substitute y in the second equation with the first equation since y = y. Thesolution<span> of the linear </span>system<span> is (1, 6). You can </span>use<span> the </span>substitution<span> method even if both equations of the linear </span>system<span> are in standard form.

Han ran 10 meters in 2.7 seconds. Priya ran 10 meters in 2.4 seconds. How long would it take han to run 50 meters.
Lina20 [59]

Hans would take 13.5 seconds to run 50 meters

Priya would take 12 seconds to run 50 meters

--------------------------------------------------------------------------------

Since they each ran 10 meters for a certain amount of time you would multiply the seconds by 5 since 10x5=50

When you do that you get

13.5 for Han's time by multiplying 2.7x5=13.5

and

12 seconds for Priya's time by multiplying 2.4x5

Solve the system of equations and choose the correct answer from the list of
Leya [2.2K]

Answer:

x = -19/2      y = -33/2

Step-by-step explanation:

x - (3x + 12) = 7

x - 3x - 12 = 7

-2x - 12 = 7

-2x = 19

x = -19/2

x - y = 7

-19/2 - y = 7

-y = 33/2

y = -33/2
