Question 606435
{{{2x-5x+6.3=-14.4}}}
combine like terms on the left side of the equation
{{{-3x + 6.3 = -14.4}}}
move the 6.3 to the right by subtracting (what you do to the left you do to the right)
{{{-3x + 6.3 - 6.3 = -14.4 - 6.3}}}
combine terms on the left
{{{-3x = -14.4 - 6.3}}}
combine terms on the right
{{{-3x = -20.7}}}
You added on the right because they are both negative.
now divide by -3
{{{(-3x)/(-3) = (-20.7)/(-3)}}}
{{{x = 6.9}}}
