Answer:

x = -7

Step-by-step explanation:

Given:

[tex] \frac{x - 1}{4} = \frac{2x + 4){5} [/tex]

Required:

Find x using cross multiplication

Solution:

Cross multiply

(2x + 4)*4 = (x - 1)*5

8x + 16 = 5x - 5

Collect like terms

8x - 5x = -16 - 5

3x = -21

Divide both sides by 3

x = -21/3

x = -7
