Question 902997
Given: {{{-2(X+7) - 5X = -6X - X}}}
Let's start by multiplying the -2 through on the left hand side.
{{{-2X - 14 - 5X = -6X - X}}}
Combine like terms
{{{-7X - 14 = -7X}}}
Add 7X to both sides
{{{-14 = 0}}}
Since -14 is not equal to 0, there are no solutions.
---------------------------------------
You can also check this by graphing the two equations.
{{{Y = -2(X+7) - 5X}}}
{{{Y = -6X - X}}}
{{{ graph( 500, 500, -50, 50, -50, 50, -2*(x+7)-5x, -6x-x) }}}
Since the lines do not intersect, there are no solutions
