Question

slove=0.3x+0.4=0.28x+1.16

Answer 1

given ,

0.3x + 0.4 = 0.28x + 1.16,

Multiply both sides with 100 for better understanding,

Now, it will be,

30x + 40 = 28x + 116,
=> 30x - 28x = 116-40,
=> 2x = 76,
=> x = 38,

Therefore x = 38, and this is the answer,

Verification,

0.3(38) + 0.4 = 0.28(38) + 1.16
=> 11.4 + 0.4 = 10.64 + 1.16
=> 11.8 = 11.8,

There the x = 38,

Hope you understand,

Have a great day !!!
