Question

a) 9x-6-2x= 64
b) 7x+9= 44
c) 4x+3= 21- 2x
d) 3x- 32=-5
e) 6x+12= 3x- 57
*AYUDA*​

Answer 1

a)

9x - 6 - 2x = 64

9x - 2x = 64 + 6

7x = 70

x = 70/7

x = 10

b)

7x + 9 = 44

7x = 44 - 9

7x = 35

x = 35/7

x = 5

c)

4x + 3 = 21 - 2x

4x + 2x = 21 - 3

6x = 18

x = 18/6

x = 3

d)

3x - 32 = -5

3x = -5 + 32

3x = 27

x = 27/3

x = 9

e)

6x + 12 = 3x - 57

6x - 3x = -57 - 12

3x = -69

x = -69/3

x = -23
