Question

-5,4-x=-3,5 x-4,7=2,34 x+7/16=3/8

Answer 1

Ответ:х=-3, 5/-5, 4.

Х=2, 34+ 4,7.

Х=3/8 -7/16

Надо провести к общему знаменателю. Х=6/16 - 7/16

Х=-1/16.

Answer 2

To solve these equations, let's go through them one by one:

Equation 1: -5.4 - x = -3.5

To isolate the variable x, we can start by adding x to both sides of the equation:

-5.4 - x + x = -3.5 + x

Simplifying, we have:

-5.4 = -3.5 + x

Next, we can subtract -3.5 from both sides of the equation:

-5.4 + 3.5 = -3.5 + x - 3.5

Simplifying further:

-1.9 = x

So the solution for Equation 1 is x = -1.9.

Equation 2: x - 4.7 = 2.34

To isolate the variable x, we can start by adding 4.7 to both sides of the equation:

x - 4.7 + 4.7 = 2.34 + 4.7

Simplifying, we have:

x = 7.04

So the solution for Equation 2 is x = 7.04.

Equation 3: x + (7/16) = 3/8

To isolate the variable x, we can start by subtracting (7/16) from both sides of the equation:

x + (7/16) - (7/16) = 3/8 - (7/16)

Simplifying, we have:

x = 3/8 - 7/16

To find a common denominator for the fractions on the right side, we can multiply the numerator and denominator of the first fraction by 2:

x = (3/8)*(2/2) - 7/16

Simplifying further:

x = 6/16 - 7/16

Now, we can subtract the fractions:

x = (6 - 7)/16

x = -1/16

So the solution for Equation 3 is x = -1/16.

In summary, the solutions for the given equations are:

Equation 1: x = -1.9 Equation 2: x = 7.04 Equation 3: x = -1/16 (or -0.0625)
