Your procedure is perfect, you're fine, however, bear in mind that, in a calculator when plugging in values for some functions, specially trigonometric ones, if you tell it cos(40), and the calculator is in Radian mode, it thinks you meant cosine of 40 radian units, if you give it cos(40) and it's in Degree mode, it thinks you meant 40°, and 40 radians is hugely different than 40°.

so, make sure your calculator is in Degree mode, as you'd have guessed, it isn't.

Answer:

<h3>The best interpretation of this equation 4x=3x is that the equation has no solution</h3>

Step-by-step explanation:

Given that Kate begins solving the equation

$\frac{2}{3}(6x-3)=\frac{1}{2}(6x-4)$

<h3>To find the best interpretation of the given equation :</h3><h3>Katie's steps are</h3>

$\frac{2}{3}(6x-3)=\frac{1}{2}(6x-4)$
$\frac{2}{3}(3(2x-1))=\frac{1}{2}((2(3x-4))$
$2(2x-1)=1(3x-2)$
$2(2x)+2(-1)=1(3x)+1(-2)$
$4x-2=3x-2$

When she adds 2 to both sides, the equation becomes

4x-2+2=3x-2+2
4x=3x

Therefore $4\neq 3$

<h3>Therefore the given equation has no solution </h3><h3>The best interpretation of this equation 4x=3x is that the equation has no solution.</h3><h3>Therefore the option no solution is correct</h3>
