Question

va rog, dau coroana ​

Answer 1

Explicație pas cu pas:

7x-7=6-3(x+1)<=>7x-7=6-3x+3<=>7x+3x=6+3+7<=>

10x=16<=>x=16:10(poti scrie sub forma de fractie)

3x-4=x+2(x-2)<=>3x-4=x+2x-4<=>3x-3x=-4+4=>nu avem solutie

x(x+1)=x²+2x+1<=>x²+x=x²+2x+1<=>x+1=0<=>x= -1

2(2x-5)=4(x-2)-6<=>4x-10=4x-8-6<=>nu avem solutie

5(1-2x)+1=4(x+3)+8<=>5-10x+1=4x+12+8<=>6-10x=4x+20

<=>-14x=14<=>x= -1

-10{-2-2[(-4)⁵:4⁴-2]}=-2x<=>-10[-2-2(-4-2)]= -2x<=>

-10(-2+12)= -2x<=> -100= -2x <=> x=50

Sper ca ai inteles
