Question

X-8=12. X+3=10. (111111111221)

Answer 1

1.x - 8 = 12
x = 12 + 8
x = 20
Ответ: 20.
2. x + 3 = 10
x = 10 - 3
x = 7
Ответ: 7.

Answer 2

X=12+8
x=20
2).x=10-3
x=7

Answer 3

Let's solve the given equations:

1. X-8 = 12: To find the value of X, we need to isolate X on one side of the equation. To do this, we can add 8 to both sides of the equation:

X - 8 + 8 = 12 + 8 X = 20

So, the solution to the first equation is X = 20.

2. X+3 = 10: Similarly, to find the value of X in this equation, we can isolate X by subtracting 3 from both sides:

X + 3 - 3 = 10 - 3 X = 7

So, the solution to the second equation is X = 7.
