Answer 2

I can help you with math problems. To simplify the expression, you need to combine the like terms. The expression can be rewritten as:

$$5.43 + x - 2.6 - 7.8 + y - 6.43$$

$$= x + y - 11.4$$

To find the value of the expression when $x = -12.6$ and $y = -3.4$, you need to substitute the values of the variables and evaluate. The value of the expression is:

$$(-12.6) + (-3.4) - 11.4$$

$$= -27.4$$

The simplified expression is $x + y - 11.4$ and its value when $x = -12.6$ and $y = -3.4$ is $-27.4$. I hope this helps.Ответь+подробно.++Упростите+выражение+и+найдите+его+значение+при+x=-12,6,y=-3,4+5,43+x+(-2,6)+(-7,8)+y+(-6,43)+
