Question

В) x + 3/10 = 1 ; г) 1 - х = 7/11

Answer 1

Ответ:

x+3/10=1

x=1-3/10

x=7/10

1-x=7/11

1-7/11=x

x=3/11

Answer 2

To solve the equations, let's go through each one step by step:

a) x + 3/10 = 1

To isolate the variable x, we can subtract 3/10 from both sides of the equation:

x + 3/10 - 3/10 = 1 - 3/10

Simplifying:

x = 1 - 3/10

To perform the subtraction, we need to find a common denominator:

x = 10/10 - 3/10

x = 7/10

Therefore, the solution for equation (a) is x = 7/10.

b) 1 - x = 7/11

To solve for x, we need to isolate it on one side of the equation. Let's start by subtracting 1 from both sides:

1 - x - 1 = 7/11 - 1

Simplifying:

-x = 7/11 - 1

To subtract fractions, we need a common denominator:

-x = 7/11 - 11/11

-x = (7 - 11)/11

-x = -4/11

To solve for x, we can multiply both sides of the equation by -1:

x = (-4/11) * (-1)

x = 4/11

Therefore, the solution for equation (b) is x = 4/11.
