Question

0,5(0,6x+7)-0,8(0,3x+4)=0,04x+1,3

Answer 1

Ответ:

Пошаговое объяснение:

0,3х + 3,5 - 0,24х - 3,2 = 0,04х + 1,3

0,3х - 0,24х - 0,04х = -3,5 + 3,2 + 1,3

0,02х = 1

х = 1 : 0,02

х = 50

Answer 2

Пошаговое объяснение:

0,5(0,6х + 7) - 0,8(0,3х + 4) = 0,04х + 1,3

0,3х + 3,5 - 0,24х - 3,2 = 0,04х + 1,3

0,06х + 0,3 = 0,04х + 1,3

0,06х - 0,04х = 1,3 - 0,3

0,02х = 1

х = 1 : 0,02

х = 50

Answer 3

To solve the equation:

0.5(0.6x + 7) - 0.8(0.3x + 4) = 0.04x + 1.3

Let's simplify and solve step by step:

0.5(0.6x + 7) - 0.8(0.3x + 4) = 0.04x + 1.3

Multiply within the parentheses:

0.3x + 3.5 - 0.24x - 3.2 = 0.04x + 1.3

Combine like terms:

0.3x - 0.24x + 3.5 - 3.2 = 0.04x + 1.3

0.06x + 0.3 = 0.04x + 1.3

Subtract 0.04x from both sides:

0.06x - 0.04x + 0.3 = 1.3

0.02x + 0.3 = 1.3

Subtract 0.3 from both sides:

0.02x = 1.3 - 0.3

0.02x = 1.0

Divide by 0.02:

x = 1.0 / 0.02

x = 50

Therefore, the solution to the equation is x = 50.
