Ecuaciones

a) 2x -1=3(2x-15)
b) 2(x-2)=-(4-x)
c) 2y-3=y+5
d) 2(3x-49)=-x+14
e) 25-2x=3x-35

Answer 1

Explicación paso a paso:

a 2x-1=3(2x-15)

2x-1=6x-45

45-1=6x-2x

44=4x

44÷4=X

X=11

b 2(x-2)=-(4-x)

2x-4=-4+X

2x-x=4-4

x=0

c 2y- 3= y+5

2y-y=5+3

y=8

d 2(3x-49)=-x+14

6x-98=-x+14

6x+x=14+98

7x= 112

x=112÷7

x=16

e 25-2x=3x-35

25+35=3x+2x

60=5x

60÷5=X

x=12
