Answer:

2. 2x-13= 14

2x= 14+13

2x= 27

x= 27/2; this is the number

3. 2a-7= 15

2a= 15+7

2a= 22

a= 11; eleven is the number

4. 3p+6= 30

3p= 30-6

3p= 24

p= 8: this is the number

[tex]5. \: \frac{x}{2} + 16 = 60[/tex]

[tex] \frac{x}{2} = 60 - 16[/tex]

[tex] \frac{x}{2} = 44[/tex]

use the cross multiply.

x= 88; the number is eighty-eight

learning task 2;

68= 3y

---- ----

3 3

y= 68/3

3y-4= 0

3y= 4

y= 3/4

3n= 0

n= 0, because any fraction that has a

numerator of zero, it is zero.

5y= 125

y= 25

x-(-27) = 35-12

x+27 = 23

x = 23-27

x = -4

5x+(-55) = 20

5x-55 = 20

5x = 20+55

5x = 75

x = 15

96-4x = -28

-4x = -96-28

-4x = -124

x = 31

41+3x = -23-18

3x = -41-41

3x = -82

x = -82/3
