<span>6 + 8x - 9 = 11x + 14 - 3x
8x + 3x - 11x = 14 + 9 -6
11x - 11x = 17
0 =17 This is not true.
When we have this kind of format, we know it is Never true.

I added a screenshot with the head of the question
Answer:sin (140°)
Explanation:Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.
Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°
Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.
Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)
Hope this helps :)
Step-by-step explanation:
5/2 times x = 1
5/2 * x = 1
5x =2
x = 2/5
x = 0.4
