Answer 1

5a - 1 = 14

5a = 14 + 1  

5a = 15  

a = 15/5  

a = 3

5x - 9 = 3(x - 2)

5x − 9 = 3x − 6  

5x = 3x − 6 + 9  

5x = 3x + 3  

5x − 3x = 3  

2x = 3  

x = 3/2  

x = 1.5

4x - 8 = -4(2x - 3) + 4

$4x - 8 = -8x + 12 + 4$

$4x - 8 = -8x + 16$

$4x = -8x + 16 + 8$

 $4x = -8x + 24$

$4x + 8x = 24$  

$12x = 24$

$x =\frac{24}{12}$  

x = 2
