Question

500 - 24 - x - 2 x = 125

x + 2 x + x + 100 = 750​

Answer 1

$500 - 54 - x - 2x = 125 \\ 500 - 54 - 125 = 3 x \\ 321 = 3 x \\ 321 \div 3 = x \\ 107 = x \\ verificacion \\ 500 - 54 - 107 - 2 \times 107 = 125 \\ 339 - 214 = 125 \\ 125 = 125$

$x + 2x + x + 100 = 750 \\ 4x = 750 - 100 \\ 4x = 650 \\ x = 650 \div 4 \\ x = 162.5$
