Question

Решите уравнение 51:(2 4/5 х - 50)=1 1/2

Answer 1

51:1 1/2=2 4/5х-50
34+50=2 4/5х
84=2 4/5х
х=84: 2 4/5
х=30

Answer 2

51 / (2 + 4/5 + x - 50) = 1 + 1/2

First, let's simplify the expression inside the parentheses: 2 + 4/5 + x - 50 = 2 + 0.8 + x - 50 = 2.8 + x - 50

Now, let's substitute this expression back into the original equation: 51 / (2.8 + x - 50) = 1 + 1/2

Now, let's simplify the left side of the equation: 51 / (2.8 + x - 50) = 1 + 1/2 51 / (x - 47.2) = 1.5

Now, let's solve for x: 51 = 1.5(x - 47.2) 51 = 1.5x - 70.8 51 + 70.8 = 1.5x 121.8 = 1.5x x = 121.8 / 1.5 x = 81.2

So the solution to the equation is x = 81.2.
