Question

0.3x+0.4=0.28x+1.16x,then x =​

Answer 1

Answer:

multiply whole equation by 100

Step-by-step explanation:

$300 + 400 = 28x + 116 x \\ 700 = 144x \\ x = \frac{700}{144 } \\ x = \frac{350}{72} \\ x = \frac{175}{36 }$

Answer 2

Answer:

x = 20/57

OR

x = 0.35 (approx)

Step-by-step explanation:

>> 0.3x + 0.4 = 0.28x + 1.16x

Multiplying the Equation on both the sides with 100

>> 30x + 40 = 28x + 116x

>> 30x + 40 = 144x

>> 144x - 30x = 40

>> 114x = 40

>> x = 40/114

>> x = 20/57

>> x = 0.35 (approx)
