Question

10x+1,5*(2,3-1,7)=13,9

Answer 1

10х+1,5*0,6=13,9

10х+0,9=13,9

10х= 13,9-0,9

10х=13

х=13\10

Answer 2

Let's solve the equation step by step:

1. Distribute the multiplication: 10x + 1.5 * 2.3 - 1.5 * 1.7 = 13.9

2. Perform the multiplication operations: 10x + 3.45 - 2.55 = 13.9

3. Combine the constant terms: 10x + 0.9 = 13.9

4. Isolate the variable term by subtracting 0.9 from both sides: 10x = 13.9 - 0.9 10x = 13.0

5. Finally, solve for x by dividing both sides by 10: x = 13.0 / 10 x = 1.3

So, the value of x that satisfies the equation is x = 1.3.
