Question

7х+2-1/7*7х+1-14*7х-1+2*7х=48

Answer 1

Ответ:

$7x+2-\frac{1}{7} *7x+1-14*7x-1+2*7x=48\\\\7x-x-98x+14x=48-2-1+1\\\\-92x=46\\\\x=-0.5$

Answer 2

To solve the equation, let's simplify the expression on the left-hand side step by step:

7x + 2 - (1/7) * 7x + 1 - 14 * 7x - 1 + 2 * 7x = 48

Start by simplifying the terms within parentheses and performing the multiplications:

7x + 2 - (1) * x + 1 - 14 * 7x - 1 + 2 * 7x = 48 7x + 2 - x + 1 - 14 * 7x - 1 + 2 * 7x = 48 7x + 2 - x + 1 - 98x - 1 + 14x = 48

Next, combine like terms:

(7x - x + 14x) + (2 + 1 - 1) + (-98x) = 48 20x + 2 = 48 - 2 + 1 20x + 2 = 47

Now, isolate the variable x by subtracting 2 from both sides:

20x + 2 - 2 = 47 - 2 20x = 45

Finally, divide both sides by 20 to solve for x:

x = 45 / 20 x = 9/4 or 2.25

Therefore, the solution to the equation is x = 9/4 or x = 2.25.
