2x + 4y = 16
4x + 8y = -16 he chooses to eliminate the variable y

These system of equations have no solution.

Step-by-step explanation:

We need to solve the system of equations

by eliminating variable y

Let:

Multiply eq(1) by 2 and subtract both equations

As 0≠48

So, these system of equations have no solution.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
