Question

(3x-5)*0,3-0,2*(9x-6)-(-1,2-0,9x)=0,9

Answer 1

(3x-5)*0,3-0,2(9x-6)-(-1,2-0,9x)=0,9

0,9x-1,5-1,8x+1,2+1,2+0,9x=0,9
2,4-1,5=0,9
0,9=0,9

Answer 2

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

(3x - 5) * 0.3 - 0.2 * (9x - 6) - (-1.2 - 0.9x) = 0.9

Step 1: Distribute the multiplication.

0.9x - 1.5 - 1.8x + 1.2 + 0.9x = 0.9

Step 2: Combine like terms.

(0.9x - 1.8x + 0.9x) - 1.5 + 1.2 = 0.9

Step 3: Simplify.

0.9x = 0.9 + 0.3

Step 4: Combine constants.

0.9x = 1.2

Step 5: Solve for x.

x = 1.2 / 0.9

x = 1.333...

Therefore, the solution to the equation is x ≈ 1.333... (repeating decimal).
