Question

1) 11X – 24 = 5X + 18
2) 24X – 15 – 7X = 11X + 12 – 3x
3) 9(3x – 2) – 2x = 3(x + 10) – 4
4) 6(2x – 2) – 5 = 4(x + 4) + 7
5) 9X – 21 < 5X + 11

Answer 1

Respuesta:

a. 7

b. 3

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
