Question

Find the value of x .

$(i). \: 25x + 35x + 65x + 100x = 1000$
$(ii). \: 5000 = 850x + 650x + 100x + 980x + 400x$
​

Answer 1

$\bf{i) 25x + 35x + 65x + 100x = 1000}$

$⟼ \sf{225x = 1000}$

$⟼ \sf{x = \frac{1000}{225} }$

$⟼ \sf{ x = \frac{40}{9} }$

$⟼ \sf{x = 4.444}$

$\bf{ii) 5000 = 850x + 650x + 100x + 980x + 400x}$

$⟼ \sf{5000 = 2980x}$

$⟼ \sf{x = \frac{5000}{2980} }$

$⟼ \sf{x = 1.6779}$
