Solve the system of linear equations. separate the x- and y- values with a coma. 20x=-58-2y

1 answer:

6 0

The best way to solve is by using elimination method.
20x = -58 - 2y
17x = -49 - 2y
Multiply second equation by -1
20x = -58 - 2y
-17x = 49 + 2y
Add equations.
3x = -9
Divide.
x = -3
Plug in -3 into one of the equations.
17(-3) = -49 - 2y
-51 = -49 - 2y
Add 49 to both sides.
-2 = -2y
Divide.
1 = y
So your solution is (-3, 1).
I hope this helps love! :)

The ordinate is twice the abscissa

zepelin [54]

We can construct the function:

$f(x)=2x$

Where $f(x)$ or $y$ is ordinate and $x$ is abscissa.

The function actually represents a line. Since it can have linear form.

$f(x)=2x+0$

Hope this helps.

For every 1/4 metric ton it takes 1/8 hours
then multipling by 8 to make the hours =1
for every 2 metric tons it take 1 hour
so the quotient is 2 metric tons per 1 hour
