Question

Д)5/6 - 2х =-1/12 ж)-5/7 +3х=1/7 и)-3/4х + х/6=1/2

Answer 1

Д) 5/6 -2х = -1/12
-2х=-1/12-5/6
-2х=-11/12
х=11/24

ж)-5/7 +3х=1/7
3х=1/7+5/7
3х=6/7
х=6/21=2/7

и) -3/4х+х/6=1/2
-7/12х=1/2
х=-7/24

Answer 2

Д) 5/6 - 2x = -1/12 To solve for x, you can isolate x on one side of the equation:

First, let's get rid of the fraction by multiplying both sides of the equation by 12 (the least common multiple of 6 and 12):

(5/6 - 2x) * 12 = (-1/12) * 12

10 - 24x = -1

Now, isolate x by moving the constant to the other side:

10 + 1 = 24x

11 = 24x

Now, divide by 24 to find the value of x:

x = 11/24

So the solution is x = 11/24.

Ж) -5/7 + 3x = 1/7 To solve for x, isolate x on one side of the equation:

First, add 5/7 to both sides of the equation to move the -5/7 to the other side:

-5/7 + 5/7 + 3x = 1/7 + 5/7

3x = 6/7

Now, divide by 3 to find the value of x:

x = (6/7) / 3

x = 2/7

So the solution is x = 2/7.

И) -3/4x + x/6 = 1/2 To solve for x, first find a common denominator for the fractions in the equation. In this case, the common denominator is 12.

Rewrite the equation with the common denominator:

(-9/12)x + (2/12)x = 6/12

Now, combine the terms on the left side of the equation:

(-9/12 + 2/12)x = 6/12

(-7/12)x = 6/12

Now, isolate x by dividing both sides by -7/12, which is the same as multiplying by -12/7:

x = (6/12) / (-7/12)

x = (6/12) * (-12/7)

x = -72/84

Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 12:

x = -6/7

So the solution is x = -6/7.
