Question

X – (5x – (2x – (1 + 3x) + x) + 3) = 8 – x x = ?

Answer 1

Відповідь:

x = -4

Пояснення:

x – (5x – (2x – (1 + 3x) + x) + 3) = 8 – x

x – (5x – (2x – 1 - 3x + x) + 3) = 8 – x

x – (5x – (-1) + 3) = 8 – x

x – (5x + 1 + 3) = 8 – x

x – (5x + 4) = 8 – x

x – 5x - 4 = 8 – x

-4x - 4 = 8 – x

-4x + x = 8 + 4

-3x = 12

x = -4

Answer 2

To solve the given equation, let's simplify and solve step by step:

X – (5x – (2x – (1 + 3x) + x) + 3) = 8 – x

First, let's simplify the innermost parentheses:

X – (5x – (2x – (1 + 3x) + x) + 3) = 8 – x X – (5x – (2x – 1 - 3x + x) + 3) = 8 – x X – (5x – (2x - 2x - 3x + x) + 3) = 8 – x X – (5x – (-2x + x) + 3) = 8 – x X – (5x – (-x) + 3) = 8 – x

Now simplify the remaining parentheses:

X – (5x – (-x) + 3) = 8 – x X – (5x + x + 3) = 8 – x X – 6x – 3 = 8 – x

Next, combine like terms:

X – 6x – 3 = 8 – x X – x – 6x – 3 = 8 – x X – 7x – 3 = 8 – x

Now, isolate the variables on one side and the constants on the other side:

X – 7x – 3 + x = 8 – x + x X – 6x – 3 = 8

X – 6x = 8 + 3 X – 6x = 11

Finally, combine like terms and solve for X:

-5x = 11 x = 11 / -5 x = -11/5

Therefore, the value of x is -11/5.
