Explicación paso a paso:

1) 11x-24=5x+18

11x-5x-24=18

6x-24=18

6x=24+18

6x=42

x=$\frac{42}{6}$

x=7

2) 24x-15-7x=11x+12-3x

24x-7x-15=11x-3x+12

17x-15=8x+12

17x-8x-15=12

9x=12+15

9x=27

x=$\frac{27}{9}$

x=3

3) 9(3x-2)-2x=3(x+10)-4

27x-18-2x=3x+30-4

27x-2-18=3x+26

25x-18=3x+26

25x-3x-18=26

22x-18=26

22x=26+18

22x=44

x=$\frac{44}{22}$

x=2

4) 6(2x-2)-5=4(x+4)+7

12x-12-5=4x-16+7

12x-17=4x+23

12x-4x-17=23

8x-17=23

8x=23+17

8x=40

x=$\frac{40}{8}$

x=5

c. 2

d. 4

e. 8

Explicación paso a paso:

1.

11x –24 = 5x +18

11 -5x = 18 +24

6x = 42

x = $\frac{42}{6}$

x = 7

2.

24x –15 –7x = 11x +12 –3x

24x -7x -11x +3x = 12 +15

9x = 27

x = $\frac{27}{9}$

x = 3

3.

9(3x –2) –2x = 3(x +10) –4

27x -18 -2x = 3x +30 -4

27x -2x -3x = 30 -4 +18

22x = 44

x = $\frac{44}{22}$

x = 2

4.

6(2x –2) –5 = 4(x + 4) +7

12x -12 -5 = 4x +16 +7

12x -4x = 16 +7 +12 +5

8x = 40

x = $\frac{40}{8}$

x = 5

5.

9x –21 < 5x +11

9x -5x < 11 +21

4x < 32

x < $\frac{32}{4}$

x < 8
