Question

Comprobacion de 5(x-1)+16(2x+3)=3(2x-7)-x

Answer 1

Respuesta:

Explicación:

5(x-1)+16(2x+3)=3(2x-7) -x

5x-5+32x+48 = 6x-21-x

5x+32x-6x+x = -21+5-48

32x = -64

x = -64/32

x=-2

2(3x-3)-4(5x-3)=x(x-3)-x(x+5)

6x-6-20x+12 = x^2-3x-x^2-5x

6x-20x-x^2+3x+x^2-5x = 6-12

-16x = -6

x= 0.375

184-7(2x+5)=301+6(x-1)-6

184-14x-35 = 301+6x-6-6

-14x-6x = 301-6-6-184+35

-20x = 140

x=140/-20

x=-7

7(18-x)-6(3-5x)=-(7x+9)-3(2x+5)-12

126-7x-18+30x = -7x-9-6x-15-12

-7x+30x+7x+6x = -9-15-12-126+18

36x = -144

x=-144/36

x= -4
