Question

2x + 10 – 4 = 26 que numero é o x

Answer 1

$2x+10-4=26\\2x+6=26\\2x-20=0\\1^{2}x+1x-20=0\\1=\frac{-x+\sqrt{x^{2}+80x}}{2x}\\1=\frac{-x+x\sqrt{1+\frac{80}{x}}}{2x}\\1=\frac{-1+\sqrt{1+\frac{80}{x}}}{2}\\2=-1+\sqrt{1+\frac{80}{x}}\\9=1+\frac{80}{x}\\8=\frac{80}{x}\\x=10$

Thats how REAL men solve equations

Bons estudos.
