-8х+9х=2-15
х=-13

Answer 3

To solve the equation 15-8x=2-9x, follow these steps:

Step 1: Move the variable terms (terms with x) to one side of the equation and the constant terms to the other side. You can do this by adding 9x to both sides of the equation:

15 - 8x + 9x = 2 - 9x + 9x

Simplifying the equation:

15 + x = 2

Step 2: Isolate the variable x on one side of the equation. To do this, subtract 15 from both sides:

15 + x - 15 = 2 - 15

Simplifying the equation:

x = -13

Step 3: Check your solution by substituting x back into the original equation:

15 - 8(-13) = 2 - 9(-13)

Simplifying both sides:

15 + 104 = 2 + 117

119 = 119

Since both sides of the equation are equal when x = -13, the solution is correct.

Therefore, the solution to the equation is x = -13.
