| (1 – y) = 15;

Let’s expand the brackets.

1 – y = 15;

To calculate the solution to an equation, you must first separate the x values from the numbers. To do this, on one side of the equation we write down the values of x, and on the other side there are known numbers.

-y = 15 – 1;

-y = 14;

y = -14/1;

y = -14;

Examination:

We substitute the found value for y into the original equation and compare the results.

(1 – (-14)) = 15;

(1 + 14) = 15;

15 = 15;

Right;

Answer: y = -14.
