Question

37,4 - x : 4,09 = 18,74

Answer 1

37,4 - x : 4,09 = 18,74

x : 4,09 = 37,4 - 18,74

x : 4,09 = 18,66

x = 18,66 × 4,09

x = 76, 3194

Answer 2

$37.4 - x \div 4.09 = 18.74 \\ x = 76.32 \\ - \frac{x}{4.09} = 18.47 - 37.4 \\ - 0.244498777506112249 = - 18.06 \\ x = \frac{18.66}{0.24449877750611249} = 76.32$
