Question

(50-32)-x=15 x+12=27 x+(21-9)=27 18-x=15

Answer 1

(50-32) - х = 18-х

х+12 = х+(21-9)

$(50 - 32 )- x = 15 \\ 18 - x = 15 \\ - x = - 3 \\ x = 3$

$x + 12 = 27 \\ x = 27 - 12 \\ x = 15$

$x + (21 - 9) = 27 \\ x + 12 = 27 \\ x = 27 - 12 \\ x = 15$

$18 - x = 15 \\ - x = - 3 \\ x = 3$

Answer 2

Ответ:(50-32)-х=15

х=50-32

х=18

х=18-15

х=3

(50-32)-3=15

15=15

х+12=27

х=27-12

х=15

15+12=27

27=27

х+(21-9)=27

х=21-9

х=12

х=27-12

х=15

15+(21-9)=27

27=27

18-х=15

х=18-15

х=3

18-3=15

15=15

Answer 3

Let's solve each of these equations step by step:

1. (50 - 32) - x = 15

First, simplify the expression within the parentheses:

(50 - 32) - x = 15 18 - x = 15

Now, isolate x by moving 18 to the other side of the equation:

• x = 15 - 18
• x = -3

So, x = -3.

2. x + 12 = 27

To solve for x, subtract 12 from both sides of the equation:

x + 12 = 27 x = 27 - 12 x = 15

So, x = 15.

3. x + (21 - 9) = 27

First, simplify the expression within the parentheses:

x + (21 - 9) = 27 x + 12 = 27

Now, isolate x by moving 12 to the other side of the equation:

x = 27 - 12 x = 15

So, x = 15.

4. 18 - x = 15

To solve for x, move 18 to the other side of the equation:

18 - x = 15 -x = 15 - 18 -x = -3

Now, multiply both sides by -1 to isolate x:

x = -3

So, x = -3.

In all four equations, the value of x is -3.
