PLEASE HELP!! Solve system of equations
I think you use desmos but mine isn’t working

The solution of system of equations is (1 , 5)

Step-by-step explanation:  

The first equation is:

3y + 2x = 17  

The second equation is:

-x - 4y = -12  

3y + 2x = 17 :

For x = 0 , y = 5.67

For x = 1 , y = 5

For x = 2 . y = 4.33

For x = 3 , y = 3.67

For x = 4, y = 3  

-x - 4y = -21 :

For x = 0 , y = 5.25

For x = 1 , y = 5

For x = 2 . y = 4.75

For x = 3 , y = 4.5

For x = 4, y = 4.25  

Solve the system of Equations:

3y + 2x = 17  ⇒  a

-x - 4y = -21  ⇒  b

Multiply equation b by -1:

x + 4y = 21

Rearrange:

x = 21 - 4y

Substitute x into equation a:

3y + 2(21-4y) = 17

3y + 42 - 8y = 17

-5y = 17 - 42

-5y = -25

y = 5

Substitute y in equation b:

-x - 4(5) = -21

-x -20 = -21

-x = -21+20

-x = -1

x = 1
