Answer 1

-x+y=2
y=2+x

5/3*x-2y=-2
5/3*x- 2 (2+x)= -2
5/3*x-4-2x=-2
5/3x -2x=4-2
x(5/3-2)=2
x(5/3-6/3)=6/3
x*(-1/3)=6/3
-x=6
x=-6
y=x+2
y=-6+2
y=-4

Answer 2

Answer:

The solution of the given system of equation is (-6,-4)

Step-by-step explanation:

Given system of equations $\frac{5}{3}x-2y=-2 \\\\-x+y=2$

We have to solve the given system of equation

Consider the given system

$\frac{5}{3}x-2y=-2$  .........(1)

$-x+y=2$ .......(2)

We first simplify the equation (1) , we have

Multiply whole equation by 3,

$5x-6y=-6$   ...........(3)

Multiply equation (2) by 5 , we have

$-5x+5y=10$   ..........(4)

Now add equation (3) and (4) , we have

$5x-6y+(-5x+5y)=-6+10$  

$5x-6y-5x+5y=4$  

$-y=4$  

$y=-4$

Substitute y = - 4 in (2) , we get

$-x+(-4)=2$

$\Rightarrow -x=2+4=6$

[tex]\Rightarrow x=-6[/tex]

Thus, x = -6 and y = -4

The solution of the given system of equation is (-6,-4)
