8 - 2 = 6
6 - 1 = 5
9 x 5 = 45
<em>Answer:</em>
<em>The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation.
</em>
<em>
</em>
<em>The equation −
2
( x + 3 ) = −
2
x − 6 does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation.
</em>
<em>
We have −
2
( x + 3 ) means that each term inside the parenthesis should be multiplied with −
2
, i.e.</em>
<em>
−
2
( x + 3
) = −
2 ⋅ x − 2 ⋅ ( + 3
) = −
2
x − 6
</em>
<em>
</em>
<em>Which is exactly what the right side says.
</em>
<em>
</em>
<em>Any value of x will, therefore, fulfill this equation.</em>
