Question

-1,5(3x+2)-8(x+1)=15

Answer 1

-4,5х-3-8х-8=15
-12,5х=26
Х=-2,08

Answer 2

-4,5х-3-8х-8=15
-12,5х-11=15
-12,5х=15+11
-12,5х=26
х=26:(-12,5)
х=-2,08

Answer 3

To solve the equation -1.5(3x + 2) - 8(x + 1) = 15, we can follow these steps:

Step 1: Distribute the -1.5 and -8 across the parentheses: -1.5 * 3x = -4.5x -1.5 * 2 = -3 -8 * x = -8x -8 * 1 = -8

The equation becomes: -4.5x - 3 - 8x - 8 = 15

Step 2: Combine like terms on the left side of the equation: -4.5x - 8x - 3 - 8 = 15 -12.5x - 11 = 15

Step 3: Move the constant term to the right side of the equation by adding 11 to both sides: -12.5x - 11 + 11 = 15 + 11 -12.5x = 26

Step 4: Divide both sides of the equation by -12.5 to solve for x: (-12.5x)/(-12.5) = 26/(-12.5) x = -2.08

So, the solution to the equation is x = -2.08.
