Question

Решите уравнение:$2,4 ( x+ 0,98) = 4,08.$

Answer 1

$2.4(x + 0.98) = 4.08$

$x + 0.98 = 1.7$

$x = 1.7 - 0.98$

$x = 0.72$

Проверка:

$2.4(0.72 + 0.98) = 4.08$

Answer 2

$2.4(x + 0.98) = 4.08 \\ 2.4x + 2.352 = 4.08 \\ 2.4x = 4.08 - 2.352 \\ 2.4x = 1.728 \\ x = 1.728 \div 2.4 \\ x = 0.72$
