Question

-2(4-5x)-3(4-5x)=10 решить уравнение​

Answer 1

Ответ:

-2(4-5x)-3(4-5x)=10

-8+10х-12+15х=10

25х=10+8+12

25х=30

х=30/25

х=1,2

Answer 2

To solve the equation, we'll start by simplifying it step by step:

1. Distribute the coefficients on the left side: -2(4 - 5x) - 3(4 - 5x) = 10

Apply the distributive property: -8 + 10x - 12 + 15x = 10

2. Combine like terms: (10x + 15x) + (-8 - 12) = 10

Combine x terms and constants separately: 25x - 20 = 10

3. Isolate the variable term (25x) on one side by adding 20 to both sides: 25x = 10 + 20

4. Simplify the right side: 25x = 30

5. Finally, solve for x by dividing both sides by 25: x = 30 / 25 x = 6 / 5

So the solution to the equation is: x = 6/5 or 1.2
