Question

5) x + 9 = 0;6)4y+8=0​

Answer 1

Ответ:

$x + 9 = 0 \\ x = 0 - 9 \\ x = - 9 \\ \\ \\ 4y + 8 = 0 \\ 4y = 0 - 8 \\ 4y = - 8 \\ y = - 8 \div 4 \\ y = - 2$

Answer 2

To solve the equations:

5. x + 9 = 0

To find the value of x, we need to isolate it on one side of the equation. We can do that by subtracting 9 from both sides:

x + 9 - 9 = 0 - 9 x = -9

Therefore, the solution for x is x = -9.

6. 4y + 8 = 0

Similar to the previous equation, we'll isolate y by subtracting 8 from both sides:

4y + 8 - 8 = 0 - 8 4y = -8

Next, divide both sides of the equation by 4 to solve for y:

4y/4 = -8/4 y = -2

Hence, the solution for y is y = -2.
