Question

1)16a-7a+96=222 2)20y+5y+y+19=227

Answer 1

Ответ:

1. 16а-7а=222-96

9а=126

а=126:9

а= 14

2.

20у+5у+у=227-19

26у=208

у=208:26

у=8

Answer 2

To solve these equations, you'll need to isolate the variable on one side of the equation. Here's how you can do it for each equation:

1. 16a - 7a + 96 = 222

Combine like terms on the left side of the equation:

(16a - 7a) + 96 = 222 9a + 96 = 222

Now, subtract 96 from both sides to isolate the variable "a":

9a = 222 - 96 9a = 126

Finally, divide both sides by 9 to solve for "a":

a = 126 / 9 a = 14

So, the solution for the first equation is a = 14.

2. 20y + 5y + y + 19 = 227

Combine like terms on the left side of the equation:

(20y + 5y + y) + 19 = 227 26y + 19 = 227

Now, subtract 19 from both sides to isolate the variable "y":

26y = 227 - 19 26y = 208

Finally, divide both sides by 26 to solve for "y":

y = 208 / 26 y = 8

So, the solution for the second equation is y = 8.
