Answer 2

To solve the equation, let's simplify it step by step:

213 * 2 - (17 + y) = 126:14

First, let's perform the multiplication:

426 - (17 + y) = 126:14

Next, let's simplify the addition within the parentheses:

426 - (17 + y) = 126:14

426 - 17 - y = 126:14

Now, let's subtract 17 from 426:

409 - y = 126:14

To simplify the right side of the equation, let's convert 126:14 to decimal form:

126 ÷ 14 = 9

Therefore, the equation becomes:

409 - y = 9

To isolate the variable y, let's subtract 409 from both sides of the equation:

• y = 9 - 409

Simplifying further:

• y = -400

Finally, let's multiply both sides of the equation by -1 to solve for y:

y = 400

Therefore, the solution to the equation is y = 400.
