Question

X:4=27-9; 8*x=34+38. 15:x=15*1

Answer 1

X:4 = 27-9 8×x=34+38 15:x = 15×1
1 15:x=15×1, x не = 0
- x = 18 8x = 72 15
4 -- = 15
x=9 x
x=72
15=15x
1 = x
x=1, x не = 0
x = 1

Answer 2

Let's solve the equations step by step:

1. X:4 = 27-9 To solve for X, we need to isolate X on one side of the equation. We can do this by performing the operations in reverse order. X/4 = 27 - 9 X/4 = 18 Now, to find the value of X, we can multiply both sides by 4: X = 18 * 4 X = 72

2. 8x = 34 + 38 To find the value of x, we first need to isolate it on one side of the equation. We can do this by performing the operations in reverse order. 8x = 34 + 38 8*x = 72 Now, to find the value of x, we can divide both sides by 8: x = 72 / 8 x = 9

3. 15:x = 15 * 1 To find the value of x, we need to isolate it on one side of the equation. We can do this by performing the operations in reverse order. 15:x = 15 * 1 To isolate x, we can multiply both sides by x: 15 = 15 * x Now, to find the value of x, we can divide both sides by 15: x = 15 / 15 x = 1

So, the solutions to the equations are: X = 72 x = 9 x = 1
