Answer:
see explanation
Step-by-step explanation:
(a)
4(x - 4) = 8 ( divide both sides by 4 )
x - 4 = 2 ( add 4 to both sides )
x = 6
(b)
5x + [tex]\frac{1}{2}[/tex] = 3x ( multiply through by 2 to clear the fraction )
10x + 1 = 6x ( subtract 6x from both sides )
4x + 1 = 0 ( subtract 1 from both sides )
4x = - 1 ( divide both sides by 4 )
x = - [tex]\frac{1}{4}[/tex]
