Question

hallar el valor de la X 5x+[-2x+(-x+6)]=18-[-(7x+6)-(3x-24)]​

Answer 1

Respuesta:

7.5

Explicación paso a paso:

5x+[-2x+(-x+6)]=18-[-(7x+6)-(3x-24)]​

5x+[-2x-x+6]=18-[-7x-6-3x+24]​

5x+[-3x+6]=18-[-10x+18]

5x-3x+6=18+10x-18

5x-3x+6=18+10x-18

2x+6=10x

6=10x-2x

6=8x

$\frac{6}{8}$=x

.75=x

Sustituimos:

5(.75)+[-2(.75)+(-(.75)+6)]=18-[-(7(.75)+6)-(3(.75)-24)]​

3.75+[-1.5+(-.75+6)]=18-[-(5.25+6)-(2.25-24)]​

3.75+[-1.5+(5.25)]=18-[-(11.25)-(-21.75)]​

3.75+[-1.5+5.25]=18-[-11.25+21.75]​

3.75+[3.75]=18-[10.5]​

3.75+3.75=18-10.5

7.5=7.5​

Espero sea de ayuda :)
