Solve the following equations:
a) 4(x - 4) = 8

b) 5x + 1 / 2 = 3x

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 + = 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 = -
