divide by 10 on both sides it should look like this

$${\frac{{\mathtt{10}}{\mathtt{\,\times\,}}{\mathtt{x}}}{{\mathtt{10}}}} = {\frac{{\mathtt{10}}}{{\mathtt{10}}}}$$

ill let you take it from there.

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{58}}{\mathtt{\,\times\,}}{\mathtt{e}}\right)}{\mathtt{\,\times\,}}{\mathtt{5}} = {\mathtt{1.900\: \!481\: \!994\: \!12}}$$

What is etc?

What is the equation for? If the next part is 4=16 then these are all multiples of 4.

equation probably 4x 

1=4 ;(1*4=4)

2=8 ; (2*4=8)

3=12; (3*4=12)

4=16; (4*4=16)

Hopefully this helps.
