Answer:

x=−y−3

Step-by-step explanation:

Step 1: Flip the equation.

−x−3=y

Step 2: Add 3 to both sides.

−x−3+3=y+3

−x=y+3

Step 3: Divide both sides by -1.

\frac{-x}{-1} = \frac{y+3}{-1}

x=−y−3

Use the elimination method to solve the system of equations. 3x+2y=16 2x-2y=4​
Masteriza [31]

Answer:

x = 4; y = 2  

Step-by-step explanation:

(1)  3x + 2y = 16

(2)  2x – 2y =  4        Add (1) and (2)

              5x =  20     Divide each side by 5

(3)            x =    4      Substitute (3) into (2)

  2×4 – 2y =    4

       8 - 2y =     4     Subtract 16 from each side

            -2y =   -4     Divide each side by -2

              y =     2

<em>Check: </em>

(1)  3×4 + 2×2 = 16

       12  +   4   = 16

                  16 = 16

(2) 2×4 – 2×2 = 4

      8    -    4   = 4

                   4 = 4
