Question

1.Solutia reala a ecuatiei 3(x+3)-2(2-x)= 2x+3(2x-1)-4 .
2. Solutia ecuatiei (x-3)² -(2x-3)(2-x)= -3(2-x)(2+x)+1.
Va rog mult sa ma ajutati !!!!!

Answer 1

$1) \ 3(x+3)-2(2-x)=2x+3(2x-1)-4 \\\\ 3x+9-4+2x=2x+6x-3-4 \\\\ 5x+5=8x-7 \\\\ 5x-8x=-7-5 \\\\ -3x=-12 \ \ \ |(-3) \\\\ \boxed{x=4}$

$2) \ (x-3)^2-(2x-3)(2-x)=-3(2-x)(2+x)+1 \\\\ x^2-6x+9-(4x-2x^2-6+3x)=-3(4-x^2)+1 \\\\ x^2-6x+9-4x+2x^2+6-3x=-12+3x^2+1 \\\\\ 3x^2-13x+15=3x^2-11 \ \ \ |(-3x^2) \\\\ -13x+15=-11 \\\\ -13x=-11-15 \\\\ -13x=-26 \ \ \ |:(-13) \\\\ \boxed{x=2}$
