Question

Решите уравнение: 1)17x-x+5x-19=170 2)73y-y-22y+40=190 Помогите пожалуйста!!

Answer 1

1)21х-19=170
21х=170+19
21х=189
х=189÷21
х=9
2)50х+40=190
50х=190-40
50х=150
х=150÷50
х=3

Answer 2

17х-х+5х-19=170
21х=170+19
21х=189
х=189:21
х=9

73у-у-22у+40=190
50у=190-40
50у=150
у=150:50
у=3

Answer 3

Solving the Equations

Let's solve the given equations step by step:

1) 17x - x + 5x - 19 = 170

To solve this equation, we can combine like terms on both sides of the equation:

16x - 19 = 170

Next, we can isolate the variable x by adding 19 to both sides of the equation:

16x = 170 + 19 16x = 189

Finally, we can solve for x by dividing both sides of the equation by 16:

x = 189 / 16 x ≈ 11.8125

Therefore, the solution to the equation 17x - x + 5x - 19 = 170 is approximately x ≈ 11.8125.

2) 73y - y - 22y + 40 = 190

To solve this equation, we can combine like terms on both sides of the equation:

73y - y - 22y + 40 = 190

Simplifying the equation gives us:

50y + 40 = 190

Next, we can isolate the variable y by subtracting 40 from both sides of the equation:

50y = 190 - 40 50y = 150

Finally, we can solve for y by dividing both sides of the equation by 50:

y = 150 / 50 y = 3

Therefore, the solution to the equation 73y - y - 22y + 40 = 190 is y = 3.
