4(x - 10) - (-3x + 4) = -2(x + 5) - (-4x +20)
=> 4x - 40 + 3x - 4 = -2x - 10 + 4x - 20
=> 7x - 44 = 2x - 30
=> 7x - 2x = -30 + 44
=> 5x = 14
=> x = 14 : 5
=> x = 14/5
\(4\left(x-10\right)-\left(-3x+4\right)=-2\left(x+5\right)-\left(-4x+20\right)\)
\(\Rightarrow4x-40+3x-4=-2x-10+4x-20\)
\(\Rightarrow4x+3x+2x-4x=-10-20+4+40\)
\(\Rightarrow5x=14\Rightarrow x=\frac{14}{5}\)
\(4(x-10)-(-3x+4)=-2(x+5)-(-4x+20)\)
\(\Rightarrow4x-40+3x-4=(-2)x-10+4x-20\)
\(\Rightarrow7x-44=2x-30\)
\(\Rightarrow7x-2x=44-30\)
\(\Rightarrow5x=14\)
\(\Rightarrow x=\frac{14}{5}\)
