Question

b) 3 . (5x – 840) = 2 . (5x + 150)

Answer 1

3 . (5x – 840) = 2 . (5x + 150)

15x - 2520 = 10x + 300

15x - 10x = 300 + 2520

5x = 2820

x = 2820/5

x = 564

Answer 2

Oii!

$3 \times (5x - 840) = 2 \times (5x + 150) =$

$15x - 2520 = 10x + 300$

$15x - 10x = 300 + 2520$

$5x = 2820$

$x = 564$

>>> x = 564
