Question

-2+x=4,3 8,1+y=-6 5-x=1,7 Z+7/18=-2/3

Answer 1

-2 + Х = 4,3
Х = 4,3 +2
Х = 6,3
-2+6,3 = 4,3
4,3 = 4,3

8,1 + у = -6
у = -6 -8,1
у = - 14,1
8,1 - 14,1 = -6
-6 = -6

5 - Х = 1,7
Х = 5-1,7 
Х = 3,3
5-3,3 = 1,7
1,7 = 1,7

Z+ 7/18 = -2/3
Z = -2/3 - 7/18
Z =-19/18
-19/18+7/18 = -2/3
-2/3=-2/3 

Answer 2

It seems like you've provided a set of equations with variables. You want to solve for the variables in each equation. Let's solve them one by one:

1. -2 + x = 4: To solve for x, you need to isolate x on one side of the equation. Start by adding 2 to both sides:

   -2 + x + 2 = 4 + 2 x = 6

2. 3 * 8 + 1 + y = -6: First, calculate the left side of the equation:

   3 * 8 + 1 = 24 + 1 = 25

   Now subtract 25 from both sides to isolate y:

   25 + y = -6 - 25 y = -31

3. 5 - x = 1.7: Subtract 5 from both sides to solve for x:

   5 - x - 5 = 1.7 - 5 -x = -3.3

   Multiply both sides by -1 to isolate x:

   x = 3.3

4. z + 7/18 = -2/3: Subtract 7/18 from both sides:

   z + 7/18 - 7/18 = -2/3 - 7/18 z = -13/18

These are the solutions for the variables in each equation:

• x = 6
• y = -31
• x = 3.3
• z = -13/18
