Question

-6x=26-20y -8x=8-20y solve this system of linear equations

Answer 1

Answer:

Equation 1: -6x = 26 - 20yEquation 2: -8x = 8-20yStep 1: Cancel out the Ys-6x = 26 - 20y --> -6x = 26 - 20y(-8x = 8-20y) x -1 --> + 8x = -8 + 20y ------------------------ 2x = 18 x = 9Step 2: Plug in X and solve for Y (P.S. you can plus X into either of the equations)-6(9) = 26 -20y-54 = 56 - 20y-80 = -20yy = 4Step 3: Check the answer:-6(9) = 26 - 20(4)-54 = -54Therefore:x = 9 y = 4

Answer 2

Equation 1: -6x = 26 - 20y
Equation 2: -8x = 8-20y

Step 1: Cancel out the Ys

-6x = 26 - 20y --> -6x = 26 - 20y
(-8x = 8-20y) x -1 --> + 8x = -8 + 20y
------------------------
2x = 18
x = 9

Step 2: Plug in X and solve for Y (P.S. you can plus X into either of the equations)

-6(9) = 26 -20y
-54 = 56 - 20y
-80 = -20y
y = 4

Step 3: Check the answer:

-6(9) = 26 - 20(4)
-54 = -54


Therefore:

x = 9 y = 4
