Question

6x–2(5x+4)=1–7(4x+3)

Answer 1

Ответ:

x=-1/2

Пошаговое объяснение:

6x–2(5x+4)=1–7(4x+3)

6x–10x-8=1-28x-21

-4x+28x=-20+8

24x=-12

x=-12/24

x=-1/2

6x–2(5x+4)=1–7(4x+3)

6×(-1/2)-2(5×(-1/2)+4)=1-7(4×(-1/2)+3)

-3-2×3/2=1-7×1

-6=-6

Answer 2

To solve the equation 6x - 2(5x + 4) = 1 - 7(4x + 3), we'll simplify and solve for x step by step.

First, let's simplify both sides of the equation:

6x - 2(5x + 4) = 1 - 7(4x + 3)

Start by distributing the -2 to the terms inside the parentheses:

6x - 10x - 8 = 1 - 28x - 21

Next, combine like terms on both sides:

-4x - 8 = -27 - 28x

To eliminate the parentheses, distribute the -7 to the terms inside the parentheses:

-4x - 8 = -27 - 28x

Now, we can simplify further by combining the x terms:

-4x + 28x = -27 + 8

24x = -19

To isolate x, divide both sides of the equation by 24:

(24x)/24 = -19/24

x = -19/24

So the solution to the equation 6x - 2(5x + 4) = 1 - 7(4x + 3) is x = -19/24.
