Question

А) 86х+13=9х-4б) 95-13х=9+4х

Answer 1

A)86x+13=9x-4
77x=-17
x=-17/77

б)95-13x=9+4x
17x=86
x=86/17

Answer 2

I can help you with your math problems. Here are the detailed solutions:

А) $$86x + 13 = 9x - 4$$ To solve for x, we need to isolate it on one side of the equation. We can do this by subtracting 9x from both sides and then subtracting 13 from both sides. This gives us:

$$86x - 9x + 13 - 13 = 9x - 9x - 4 - 13$$ Simplifying, we get:

$$77x = -17$$ Now, we can divide both sides by 77 to get x:

$$x = \frac{-17}{77}$$ This is the final answer.

Б) $$95 - 13x = 9 + 4x$$ To solve for x, we need to isolate it on one side of the equation. We can do this by adding 13x to both sides and then subtracting 9 from both sides. This gives us:

$$95 - 13x + 13x - 9 = 9 + 4x + 13x - 9$$ Simplifying, we get:

$$86 = 17x$$ Now, we can divide both sides by 17 to get x:

$$x = \frac{86}{17}$$ This is the final answer.
