Question

-0,8(5x-18)+0,5(7x+16)=16,5x+5,4​

Answer 1

Решение:

-0,8(5x-18)+0,5(7x+16)=16,5x+5,4​

-4x - (-14,4) + 3,5х + 8 = 16,5x + 5,4

-4x + 3,5x - 16,5x = 5,4 + 14,4 - 8

-17x = 11,8

x = 11,8/17                                       −0,69411764705 ≈ -0,7

x = -0,7

Ответ x = -0,7

Answer 2

To solve the equation:

scssCopy code
-0.8(5x - 18) + 0.5(7x + 16) = 16.5x + 5.4

Follow these steps:

Step 1: Distribute the constants and variables within the parentheses:

diffCopy code
-4x + 14.4 + 3.5x + 8 = 16.5x + 5.4

Step 2: Combine like terms on both sides of the equation:

diffCopy code
-0.5x + 22.4 = 16.5x + 5.4

Step 3: Move the terms involving x to one side and the constant terms to the other side:

Subtract 16.5x from both sides:

diffCopy code
-0.5x - 16.5x + 22.4 = 5.4
-17x + 22.4 = 5.4

Subtract 22.4 from both sides:

diffCopy code
-17x = -17

Step 4: Solve for x by dividing both sides by -17:

x = 1

So, the solution to the equation is x = 1.
