Question

X -12 = 0 25+x=25 x:108=1 y:1 = 37 x×15= 0 X × 18 = 18

Answer 1

X-12=0
x=12+0
x=12

25+x=25
x=25-25
x=0

x:108=1
x=108•1
x=108

y:1=37
y=37•1
y=37

x•15=0
x=0:15
x=0

x•18=18
x=18:18
x=1

Answer 2

Let's go through each equation one by one:

1. X - 12 = 0

To solve for X, we can isolate X on one side of the equation. Adding 12 to both sides:

X - 12 + 12 = 0 + 12 X = 12

So, the solution to this equation is X = 12.

2. 25 + X = 25

In this equation, we want to isolate X. To do that, we can subtract 25 from both sides:

25 + X - 25 = 25 - 25 X = 0

The solution to this equation is X = 0.

3. X : 108 = 1

Here, the symbol ":" represents division. To find X, we can multiply both sides of the equation by 108:

X : 108 * 108 = 1 * 108 X = 108

So, the solution to this equation is X = 108.

4. y : 1 = 37

Similarly, in this equation, we can multiply both sides by 1 to solve for y:

y : 1 * 1 = 37 * 1 y = 37

The solution to this equation is y = 37.

5. X × 15 = 0

To solve for X in this equation, we can divide both sides by 15:

X × 15 / 15 = 0 / 15 X = 0

The solution to this equation is X = 0.

6. X × 18 = 18

Again, we want to solve for X. To do that, we divide both sides by 18:

X × 18 / 18 = 18 / 18 X = 1

The solution to this equation is X = 1.

So, the solutions to the given equations are:

X - 12 = 0: X = 12 25 + X = 25: X = 0 X : 108 = 1: X = 108 y : 1 = 37: y = 37 X × 15 = 0: X = 0 X × 18 = 18: X = 1
