Пошаговое объяснение:

-7,1х+9х=2,8-6,6

1,9х=-3,8

Х=-3,8:1,9

Х=-2

Answer 3

To solve the equation -7 + 1x - 2.8 = -6.6 - 9x, follow these steps:

Step 1: Combine like terms on both sides of the equation to simplify it. -7 + 1x - 2.8 = -6.6 - 9x Combine -7 and -2.8 on the left side: -7 - 2.8 + 1x = -9.8 + 1x The equation becomes: -9.8 + 1x = -6.6 - 9x

Step 2: Isolate the variable x on one side of the equation. To do this, move all terms containing x to one side of the equation and the constant terms to the other side. Add 9x to both sides to move all terms with x to the left side: -9.8 + 1x + 9x = -6.6 - 9x + 9x Simplify: -8x - 9.8 = -6.6

Step 3: Now, move the constant term (-9.8) to the right side by adding 9.8 to both sides of the equation: -8x - 9.8 + 9.8 = -6.6 + 9.8 Simplify: -8x = 3.2

Step 4: Finally, solve for x by dividing both sides by -8: x = 3.2 / -8 x = -0.4

So, the value of x that satisfies the equation is x = -0.4.
