Answer:

Step-by-step explanation:

2y-3x=-27

5y+3x=6

You have to add both thee equations, this way the -3x and +3x will cancel out. So add going straight down.

(2y+5y)+(-3x+3x)=(-27+6)

7y=-21

y=-3

And from here plug in y=3 into any of the two original equations

So I picked 2y-3x=-27

2(-3) -3x=-27

-6-3x=-27

-3x=-27+6

-3x=-21

x=7

The value of x will be 7 and the value of y will be negative 3.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The equations are given below.

2y -  3x = -27  ....1

5y + 3x = 6    ....2

Add both equations, then we have

7y = -21

 y = -3

Put y = -3, in equation 1, then we have

2(-3) - 3x = -27

   -6 - 3x = -27

        -3x = -21

           x = 7
