Question 86320
Given the equation:
.
{{{-4x = -8}}}
.
To solve for x, divide both sides of the given equation by -4, the multiplier of x. When
you do this is what happens:
.
{{{(-4*x)/(-4) = (-8)/(-4)}}}
.
The minus 4 terms in the numerator and the denominator of the left side cancel:
.
{{{(cross(-4)*x)/cross(-4) = (-8)/(-4)}}}
.
and on the right side the 4 in the denominator goes into the 8 in the numerator 2 times.
The 2 is positive because when the numerator and the denominator terms have the same sign
the rule is that the answer will be positive. This makes the problem become:
.
{{{x = 2}}}
.
And that's the answer you were looking for.  Hope this helps you to understand the method
of solving an equation by dividing both sides by the multiplier of x (also called the
"coefficient of x".)
