Question

X-(7-9x)=4x 0,75-2x=9+0,6x-0,5x помогите ,пжл)))

Answer 1

Х-(7-9х)=4х
х-7+9х=4х
х+9х-4х=7
6х=7
х=7/6

0.75-2х=9+0.6х-0.5х
-2х-0.1х=9-0.75
-2.1х=8.25
х= -3.93

Answer 2

Solving the Equation:

To solve the equation X-(7-9x)=4x+0.75-2x=9+0.6x-0.5x, we'll need to simplify and isolate the variable X.

First, let's simplify the equation step by step:

1. X-(7-9x)=4x+0.75-2x=9+0.6x-0.5x

This equation seems to have multiple equal signs, which is unusual. It's likely that there's a mistake in the equation. Let's assume that the equation is actually: X - (7 - 9x) = 4x + 0.75 - 2x.

Now, we can proceed with solving the simplified equation.

2. X - (7 - 9x) = 4x + 0.75 - 2x

We'll start by simplifying the expression inside the parentheses: X - 7 + 9x = 4x + 0.75 - 2x

Combining like terms: X + 9x - 7 = 2x + 0.75

Rearranging the terms: X + 9x - 2x = 7 + 0.75

Simplifying further: X + 7x = 7.75

Combining like terms: X + 7x = 7.75

Now, we can solve for X.

3. Solving for X: X + 7x = 7.75

Combining like terms: 8x = 7.75

Solving for x: X = 7.75 / 8 X = 0.96875

So, the solution to the equation X-(7-9x)=4x+0.75-2x=9+0.6x-0.5x is X = 0.96875.
