DETAILED EXPLANATION

Look at -4%2A%2810%2Ax%2B2%29=highlight_red%28+-4+%29.
Moved these terms to the left highlight_green%28+4+%29
It becomes -4%2A%2810%2Ax%2B2%29%2Bhighlight_green%28+4+%29=0.
Look at -highlight_red%28+4%2A%2810%2Ax%2B2%29+%29%2B4=0.
Expanded term -4 by using associative property on %2810%2Ax%2B2%29
It becomes -highlight_green%28+4%2A10%2Ax+%29-highlight_green%28+4%2A2+%29%2B4=0.
Look at -highlight_red%28+4+%29%2Ahighlight_red%28+10+%29%2Ax-4%2A2%2B4=0.
Multiplied numerator integers
It becomes -highlight_green%28+40+%29%2Ax-4%2A2%2B4=0.
Look at -40%2Ax-highlight_red%28+4+%29%2Ahighlight_red%28+2+%29%2B4=0.
Multiplied numerator integers
It becomes -40%2Ax-highlight_green%28+8+%29%2B4=0.
Look at -40%2Ax-highlight_red%28+8+%29%2Bhighlight_red%28+4+%29=0.
Added fractions or integers together
It becomes -40%2Ax%2Bhighlight_green%28+-4+%29=0.
Look at -40%2Ax%2Bhighlight_red%28+-4+%29=0.
Removed extra sign in front of -4
It becomes -40%2Ax-highlight_green%28+4+%29=0.
Look at highlight_red%28+-40%2Ax-4+%29=0.
Solved linear equation highlight_red%28+-40%2Ax-4=0+%29 equivalent to -40*x-4 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: x=-0.1.

Done!

At the end when you have -40x-4=0, you can add four to both sides, making it -40x=4, then divide both sides by -40 to get x alone and x=-4%2F40 or
x=-1%2F10
