You can turn :
4 divided by 1/3 INTO 4 times 3
It's the same thing. Then make four groups of 3

Answer:
(√3+1.4)m
Step-by-step explanation:
By forming a right triangle, we can see that the angle of elevation is 30°.
In a 30-60-90 triangle, the side opposite the 30° is the other leg multiplied by 1/√3.
x= 
The height of the pole is (√3+1.4)m
Step 1:<span>Simplify both sides of the equation.</span><span><span>2<span>(<span><span>3x</span>+1</span>)</span></span>=<span>3<span>(<span>2−x</span>)</span></span></span><span><span><span><span>(2)</span><span>(<span>3x</span>)</span></span>+<span><span>(2)</span><span>(1)</span></span></span>=<span><span><span>(3)</span><span>(2)</span></span>+<span><span>(3)</span><span>(<span>−x</span>)</span></span></span></span>(Distribute)<span><span><span>6x</span>+2</span>=<span><span>6+</span>−<span>3x</span></span></span><span><span><span>6x</span>+2</span>=<span><span>−<span>3x</span></span>+6</span></span>
Step 2: Add 3x to both sides.<span><span><span><span>6x</span>+2</span>+<span>3x</span></span>=<span><span><span>−<span>3x</span></span>+6</span>+<span>3x</span></span></span><span><span><span>9x</span>+2</span>=6</span>

Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0
An example:
2(x + y) + 4 = (4x + 4y + 8)/2
2x + 2y + 4 = 2x + 2y + 4
0 = 0
