Спростіть вираз -7,4+x+12,69+(-3,6)+y+(-9,69)

Answer 1

$- 7.4 + x + 12.69 + ( - 3.6) + y + ( - 9.69) = - 7.4 + x + 12.69 - 3.6 + y - 9.69 = - 8 + x + y$

Answer 2

I can chat with you in Ukrainian. To simplify the expression, you need to combine the like terms. The like terms are the ones that have the same variable or no variable at all. For example, -7.4 and 12.69 are like terms because they have no variable. Similarly, -3.6y and -9.69y are like terms because they have the same variable y. To combine the like terms, you need to add or subtract their coefficients. The coefficient is the number that is multiplied by the variable. For example, the coefficient of -3.6y is -3.6. So, to simplify the expression, you can do the following steps:

$$ \begin{aligned} -7.4 + x + 12.69 + (-3.6)y + (-9.69) &= (-7.4 + 12.69) + x + (-3.6 - 9.69)y \\ &= 5.29 + x - 13.29y \end{aligned} $$

The final answer is $$5.29 + x - 13.29y$$. This is the simplest form of the expression. I hope this helps you understand how to simplify expressions.
