Question

resolver las ecuaciones
a)x=5(2x-3)=3(x-1)+4
b)2(x-5)/3+4=5x-2
c)3-x+2/3=(3x2)
d)3(x-4)+10=13-x

Answer 1

Explicación paso a paso:

a) x-5(2x+3)=3(x-1)+4

x-10x-15=3x - 3 +4

-9x -15= 3x+1

-15 - 1 = 3x + 9x

-16 = 12x

-4/3 =x

b) 2x - 10 + 12 = 15x - 6

2+ 6 = 15x - 2x

8 = 13x

8/13= x

c) 9-3x+2= 18

11 - 3x= 18

-7=3x

-7/3 = x

d) 3x -12 +10= 13- x

3x+x= 13 +2

4x = 15

x =15/4
