Question

(2x-5)*0,8-0,2(2x-3)-(-1,9+1,2x)=-1,5

Answer 1

(2x-5)×0,8-0,2(2x-3)-(-1,9+1,2x)=-1,5
1,6x-4-0,4x+0,6+1,9+1,2x=-1,5
2,4x-1,5=-1,5
2,4x=-1,5+1,5
2,4x=0
x=0/2,4
x=0

Answer 2

To solve the equation, let's simplify the expression step by step:

(2x - 5) * 0.8 - 0.2(2x - 3) - (-1.9 + 1.2x) = -1.5

Step 1: Distribute the constants outside the parentheses.

0.8 * 2x - 0.8 * 5 - 0.2 * 2x + 0.2 * 3 - (-1.9) + 1.2x = -1.5

Step 2: Simplify the expressions.

1.6x - 4 - 0.4x + 0.6 + 1.9 + 1.2x = -1.5

Step 3: Combine like terms.

(1.6x - 0.4x + 1.2x) - 4 + 0.6 + 1.9 = -1.5

2.4x - 4 + 2.5 = -1.5

Step 4: Continue combining like terms.

2.4x - 1.5 = -1.5

Step 5: Add 1.5 to both sides to isolate the term with 'x'.

2.4x - 1.5 + 1.5 = -1.5 + 1.5

2.4x = 0

Step 6: Divide both sides by 2.4 to solve for 'x'.

x = 0

So, the solution to the equation is x = 0.
