Answer 2

Answer:

x = - 320

Step-by-step explanation:

Given,

0.75 (x + 40) = 0.35 (x + 20) + 0.35 (x + 20)

Now solving the equation for x

0.75 x + 0.75 * 40 = 0.35 x + 0.35 * 20 + 0.35 x + 0.35 * 20

0.75 x - 0.35 x - 0.35 x =  0.35 * 20 + 0.35 * 20  - 0.75 * 40

0.05 x = 7 + 7 - 30

0.05 x = 14 - 30

x = - 16/ 0.05 = - 16/5 * 100 = - 320

Therefore, x = - 320.
