х=-3,3

Answer 2

To solve the equation −3(4−5x)+2(3−6x)=−3,9, follow these steps:

Step 1: Distribute the numbers outside the parentheses to the terms inside: -3 * 4 + 3 * 5x + 2 * 3 - 2 * 6x = -3.9

Step 2: Simplify the equation by combining like terms: -12 + 15x + 6 - 12x = -3.9

Step 3: Combine the x terms: 15x - 12x = -3.9 + 12 - 6

Step 4: Simplify further: 3x = 2.1

Step 5: Solve for x by dividing both sides by 3: x = 2.1 / 3

Step 6: Calculate the value of x: x = 0.7

So, the solution to the equation is x = 0.7.
