Question

как решить уравнение. 1/4х + 1/6х + 126=?

Answer 1

1/4+1/6=5/12

5/12х=-126

х=-126/(5/12)

х=-126*(12/5)=-302,4

 

 

Answer 2

1/4х + 1/6х + 126=

1/4х + 1/6х = - 126

 

х (1/4 + 1/6) = -126

 х (10/24) = -126

5/12 х = - 126 

х = (-126) : 5/12

х = - (126 х 12 : 5)

х = - (1512 : 5)

х = - 302, 4
