Question

6,7x+4x-0,5(10x-1,2)=18,84

Answer 1

6,7х+4х-0,5(10х-1,2)=18,84
6,7х+4х-5х+0,6=18,84
5,7х+0,6=18,84
5,7х=18,84-0,6
5,7х=18,24
х=3,2
Ответ: х=3,2

Answer 2

6,7х+4х-5x+0,6=18,84  => 5,7x+0,6=18,84 => 5,7x =18,84-0,6  =>  5,7x=18,24    =>  x=3,2

Answer 3

To solve the equation, first, let's simplify it step-by-step and then solve for the value of 'x.'

Given equation: 6.7x + 4x - 0.5(10x - 1.2) = 18.84

Step 1: Distribute the -0.5 to the terms inside the parentheses: 6.7x + 4x - 0.5 * 10x + 0.5 * 1.2 = 18.84

Step 2: Perform the multiplication: 6.7x + 4x - 5x + 0.6 = 18.84

Step 3: Combine like terms: (6.7x + 4x - 5x) + 0.6 = 18.84

Step 4: Simplify further: 5.7x + 0.6 = 18.84

Step 5: Now, isolate the variable 'x' on one side of the equation. To do that, we'll subtract 0.6 from both sides: 5.7x = 18.84 - 0.6 5.7x = 18.24

Step 6: Finally, solve for 'x' by dividing both sides by 5.7: x = 18.24 / 5.7 x ≈ 3.2

So, the value of 'x' that satisfies the equation is approximately 3.2.
