Question

Rezolvati toate ecuatiile va rog dau coroana ,,Nu dati intrebari prostesti

Answer 1

$2x+1=9\\2x=9-1=8\\x=\frac{8}{2}=4$

$4x-9=-25\\4x=-25+9\\4x=-16\\x= -\frac{16}{4} =-4$

$-6=3x+9\\3x=-6-9=-15\\x=-\frac{15}{3} =-5$

$-4x+2=10\\-4x=10-2=8\\4x=-8\\x=-\frac{8}{4} =-2$

$0-5x=8\\-5x=8\\x=-\frac{8}{5}$

$-5(x+3)=-10\\-5x-15=-10\\-5x=5\\x=-\frac{5}{5} =-1$

$-9(1-2x)=27\\-9+18x=27\\18x=27+9=36\\x=\frac{36}{18} =2$

$(x+2)*(-3)+14=2\\-3x-6+14=2\\-3x=2-14+6\\-3x=-6 |*(-1)\\3x=6\\x=\frac{6}{3} =2$

$(-2)^3+1=2(x-1)+3\\-8+1=2x-2+3\\-7=2x+1\\2x=-8\\x=-\frac{8}{2} =-4$

Sunt foarte multe exercitii, dar ti-am facut prima parte
