Question

-7(3x-4)+2(2x+3)=8 помогите подробно

Answer 1

-21х+28+4х+6=8
-21х+4х=8-28-6
-17х=-26
х=26/17

Answer 2

Sure, I'd be happy to help you solve the equation step by step. We want to find the value of "x" that satisfies the equation:

-7(3x - 4) + 2(2x + 3) = 8

Step 1: Distribute the numbers outside the parentheses.

-7 * 3x = -21x -7 * (-4) = +28

2 * 2x = 4x 2 * 3 = 6

Now the equation becomes:

-21x + 28 + 4x + 6 = 8

Step 2: Combine like terms.

Combine the x terms on the left side of the equation:

-21x + 4x = -17x

Now the equation becomes:

-17x + 28 + 6 = 8

Step 3: Continue combining like terms.

Combine the constants on the left side of the equation:

28 + 6 = 34

Now the equation becomes:

-17x + 34 = 8

Step 4: Isolate the variable "x."

To isolate the variable "x" on one side of the equation, we need to get rid of the constant term on the left side. We can do this by subtracting 34 from both sides of the equation:

-17x + 34 - 34 = 8 - 34

This simplifies to:

-17x = -26

Step 5: Solve for "x."

Finally, to find the value of "x," we need to get rid of the coefficient (-17) that is multiplied with "x." We can do this by dividing both sides of the equation by -17:

(-17x) / -17 = (-26) / -17

This simplifies to:

x = 26/17

So the solution to the equation is:

x = 26/17

That's it! We have found the value of "x" that satisfies the equation.
