Verified answer

Distribute the multiplys first

-2*x - 2*3 = -2* x - 2* 1 - 4

-2x - 6 = -2x - 2- 4

-2x - 6 = -2x - 6...........................add 2x

-6 = -6........................................This is true so there are infinite solutions possible

When variables all cancel out if what is left is True then infinite solutions

however if False then no solution is possible

X= 2
