Реши уравнение и введи значение x в поле: А) 3,2x - 1,5 = 1,7x B) 2 - (0,9x - 1,3) =...

$1)3.2x-1.5=1.7x\\3.2x-1.7x=1.5\\1.5x=1.5\\x=1.5/1.5\\x=1 \\ \\ 2)2-(0.9x-1.3)=1.3x\\2-0.9x+1.3=1.3x\\-0.9x-1.3x=-2-1.3\\-2.2x=-3.3\\x= \frac{-3.3}{-2.2} \\ x=1.5$

$3)-(3.3x+1.2)-(0.7x+1.6)=0\\-3.3x-1.2-0.7x-1.6=0\\-4x-2.8=0\\-4x=2.8\\x=-0.7 \\ \\ 4)-(4.1x+2.5)-(2.3x+3.9)=1.6x \\ -4.1x-2.5-2.3x-3.9=1.6x\\-4.1x-2.3x-1.6x=2.5+2.3\\-8x=6.4\\x=-0.8$

$5)(3.6x+2.5)-(1.8x+2.3)=1.6x\\3.6x+2.5-1.8x-2.3=1.6x\\1.8x-1.6x=2.3-2.5\\0.2x=--0.2\\x=-1$
