Answer 1

Explicación paso a paso:

1) 3+10x-15-4=4x-12+2

10x-4x= -12+2+15+4-3

6x=6

x=6/6

x=1

2)-1-12x+3+6=2+6x+12+30

-12x-6x=2+12+30+1-3-6

-18x=36

x= -36/18

x= -2

3)5/2+8/5x-12/20-1/5=3/2x+11/5

8/5x-3/2x=11/5+12/20+1/5-5/2

1/10x=10/20

x=5

4)8/3x+4/3+28/10x-42/10+3=55/12x+44/12

8/3x+14/5x-55/12x=44/12-4/3+42/10-3

-91/60x=212/60

x= -212/91

Answer 2

Explicación paso a paso:

1. 3 + 5(2X – 3) – 4 = 4(X – 3) + 2
2. – 1 – 3(4X – 1) + 6 = 2 + 3(2X + 4) + 30
3. 5/2 + ⅘(2X – ¾) – ⅕ = 3/2X + 11/5
4. 4/3(2X + 1) + 7/2(⅘X – 6/5) + 3 = 11/12(5X+4)

desarrollo;

1. ejercicio

3 + 5(2X – 3) – 4 = 4(X – 3) + 2

5(2x – 3) – 1 = 4x – 12 + 2

10x – 15 – 1 = 4x – 12 + 2

10x – 4x = – 12 + 2 + 15 + 1

6x = 6

x = 6/6

X = 1

2. ejercicio

– 1 – 3(4X – 1) + 6 = 2 + 3(2X + 4) + 30

–3(4x – 1) + 5 = 3(2x + 4) + 32

– 12x + 3 + 5 = 6x + 12 + 32

–12x – 6x = 12 + 32 – 8

–18x = 36

x = –36/18

X = –2

3. ejercicio

5/2 + ⅘(2X – ¾) – ⅕ = 3/2X + 11/5

8x / 5 – 3/5 + 23/10 = 3/2X + 11/5 /×50

10×8X – 10×3 + 5×23 = 25×3X + 10×11

80x – 30 + 115 = 75x + 110

80x – 75x = 110 – 115 + 30

5x = 25

X = 25 / 5

X = 5

4. ejercicio

4/3(2X + 1) + 7/2(⅘X – 6/5) + 3 = 11/12(5X+4)

• 7/2 y 4/3 multiplicamos por el binomio

4(2X + 1) / 3 + 7(4x – 6/5) / 2 + 3 = 11/12(5x+4)

4(2X + 1) / 3 + 7(4x – 6/5) / 2 = 11/12(5x+4) – 3

4(2X + 1) / 3 + 7(4x – 6/5) / 2 = ⅔ + 55x/12

4(2X + 1) / 3 + 7(4x – 6/5) / 2 – 55x/12 = ⅔

• MCM : 2 ; 3 ; 12 = 12

• reescribimos las fracciones en función del MCM

16(2x+1) / 12 + 42(4x – 6)/5/12 –55x / 12

16(2x+1) + 42(4x–6)/5 – 55x. / 12 = ⅔

53x – 172 / 60 = ⅔

( 53x – 172 ) = 60 × ⅔

53x – 172 = 40

53x = 40 + 172

53x = 212

X = 212 / 53

X = 4
