Answer 2

To solve each of these equations, follow these steps:

А) х + (-5) = 8

Step 1: Combine like terms on the left side of the equation. х - 5 = 8

Step 2: Isolate the variable by adding 5 to both sides of the equation. х - 5 + 5 = 8 + 5 х = 13

So, the value of x is 13.

Б) у + (-10) = -2

Step 1: Combine like terms on the left side of the equation. у - 10 = -2

Step 2: Isolate the variable by adding 10 to both sides of the equation. у - 10 + 10 = -2 + 10 у = 8

So, the value of у is 8.

В) t + 4 = -20

Step 1: Combine like terms on the left side of the equation. t + 4 = -20

Step 2: Isolate the variable by subtracting 4 from both sides of the equation. t + 4 - 4 = -20 - 4 t = -24

So, the value of t is -24.
