Question

2(х – 5) – 4(х +3) = х – 43.

Answer 1

Ответ:

x = -7

Объяснение:

2x - 10 - 4x - 12 = x - 43

-3x = 21

x = -7

Answer 2

Ответ:

2x-10-4x-12-x+43=0

21-3x=0

-3x=-21

X=7

Answer 3

To solve the given equation, let's start by simplifying the expressions on both sides and then isolate the variable "x" on one side of the equation.

Given equation: 2(x - 5) - 4(x + 3) = x - 43

Step 1: Distribute the coefficients to simplify the expressions within the parentheses.

2(x - 5) = 2x - 10 -4(x + 3) = -4x - 12

Now the equation becomes: 2x - 10 - 4x - 12 = x - 43

Step 2: Combine like terms on the left side of the equation.

(2x - 4x) + (-10 - 12) = x - 43

Simplify further:

-2x - 22 = x - 43

Step 3: Isolate "x" on one side by moving all the terms containing "x" to one side and the constants to the other side.

Add 2x to both sides:

-2x + 2x - 22 = x - 43 + 2x

Simplify:

-22 = 3x - 43

Step 4: Now, isolate "x" by moving the constant term (-43) to the other side.

Add 43 to both sides:

-22 + 43 = 3x - 43 + 43

Simplify:

21 = 3x

Step 5: Finally, solve for "x" by dividing both sides by 3.

x = 21 / 3

x = 7

So, the value of "x" that satisfies the equation is x = 7.
