Question

(7-5x)-(8-4x)=(5x+6)=8

Answer 1

может в конце +8??
7-5х-8+4х=5х+6+8
-5х+4х-5х=-7+8+6+8
-6х=15
х=-2.5 

Answer 2

может в конце (-8)???

7-5х-8+4х = 5х+6-8

-5х+4х-5х= 6-8-7+8

-6х = -1

х = 1/6

 

Answer 3

Let's solve the equation step by step.

Given equation: (7-5x) - (8-4x) = (5x + 6) = 8

First, simplify the equation by removing the parentheses:

7 - 5x - 8 + 4x = 5x + 6 = 8

Combine like terms on both sides:

-5x + 4x - 1 = 5x + 6 = 8

Combine the x terms on the left side:

-x - 1 = 5x + 6 = 8

Now, isolate the x terms on one side and the constant terms on the other side. Let's move the constant terms to the right side:

-x - 1 - 6 = 5x + 8 - 6

Simplifying:

-x - 7 = 5x + 2

Now, move the 5x term to the left side by adding 5x to both sides:

-x - 5x - 7 = 5x + 5x + 2

Simplifying:

-6x - 7 = 10x + 2

Next, move the constant term to the right side by adding 7 to both sides:

-6x - 7 + 7 = 10x + 2 + 7

Simplifying:

-6x = 10x + 9

To isolate the x term, we need to move the 10x term to the left side. Let's subtract 10x from both sides:

-6x - 10x = 10x + 9 - 10x

Simplifying:

-16x = 9

Finally, solve for x by dividing both sides by -16:

x = 9 / -16

Simplifying the fraction:

x = -9/16

Therefore, the solution to the given equation is x = -9/16.
