Question

X/13=7 , 93/x= 31, x+3/7=5, 45/6+x=5

Answer 1

Пошаговое объяснение:

х/13=7

х=7*13

х=91

93/х=31

х=93/31

х=3

х+3/7=5

х=5-3/7

х=4 4/7

45/6+х=5

х=5-45/6

х=(30-45)/6

х=-15/6

х=-5/2

х=-2,5

Answer 2

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

1. X/13 = 7: To solve for X, we can multiply both sides of the equation by 13 to eliminate the denominator: X = 7 * 13 X = 91

So the solution to the equation is X = 91.

2. 93/x = 31: To solve for X, we can cross-multiply the equation: 93 * x = 31 * x 93 = 31 * x Divide both sides of the equation by 31 to isolate X: 93/31 = x x = 3

So the solution to the equation is X = 3.

3. (X + 3)/7 = 5: To solve for X, we can start by multiplying both sides of the equation by 7 to eliminate the denominator: 7 * (X + 3)/7 = 5 * 7 (X + 3) = 35 Now subtract 3 from both sides of the equation to isolate X: X + 3 - 3 = 35 - 3 X = 32

So the solution to the equation is X = 32.

4. 45/(6 + X) = 5: To solve for X, we can start by multiplying both sides of the equation by (6 + X) to eliminate the denominator: (6 + X) * 45/(6 + X) = 5 * (6 + X) 45 = 30 + 5X Now subtract 30 from both sides of the equation to isolate X: 45 - 30 = 30 - 30 + 5X 15 = 5X Divide both sides of the equation by 5 to solve for X: 15/5 = X X = 3

So the solution to the equation is X = 3.

To summarize:

1. X = 91
2. X = 3
3. X = 32
4. X = 3
