Question

-5*1/14-1*2/7х=-2.75

Answer 1

Ответ:

$- \frac{5}{14} - \frac{2}{7x} = - 2.75 \\ \frac{2}{7x} = \frac{67}{28} \\ 56 = 469x \\ x = \frac{8}{67}$

Answer 2

To solve the equation, let's simplify the expression on the left-hand side (LHS) and then solve for the variable 'x'.

Given equation: -5 * (1/14) - 1 * (2/7) * x = -2.75

Step 1: Simplify the expression on the LHS: -5 * (1/14) = -5/14 -1 * (2/7) = -2/7

The equation becomes: (-5/14) - (2/7) * x = -2.75

Step 2: Multiply (2/7) with 'x': (-2/7) * x = -2x/7

The equation becomes: -5/14 - 2x/7 = -2.75

Step 3: Get rid of the fractions by multiplying through by the least common multiple (LCM) of the denominators, which is 14: 14 * (-5/14) - 14 * (2x/7) = 14 * (-2.75) -5 - 4x = -38.5

Step 4: Simplify and solve for 'x': -4x = -38.5 + 5 -4x = -33.5 x = (-33.5) / (-4) x = 8.375

Therefore, the solution to the equation -5 * (1/14) - 1 * (2/7) * x = -2.75 is x = 8.375.
