2х-88у-99

Пошаговое объяснение:

-5,8(10/29x-5y+9)+7,8(-6+20/39x-15y)= -58/29х+29у-52,2-46,8+156/39х-117у=

-2х+4х+29у-117у-52,2-46,8=2х-88у-99

Answer 3

To simplify the given expression, let's start by distributing the coefficients to each term within the parentheses and then combine like terms:

-5(10/29x - 5y + 9) + 7(8 - 6 + 20/39x - 15y)

Applying the distributive property:

= (-5 * 10/29x) + (-5 * -5y) + (-5 * 9) + (7 * 8) + (7 * -6) + (7 * 20/39x) + (7 * -15y)

= -50/29x + 25y - 45 + 56 - 42 + (140/39)x - 105y

Now, let's combine the like terms:

= (-50/29x + (140/39)x) + (25y - 105y) + (-45 + 56 - 42)

To add the x terms, we need a common denominator for -50/29 and 140/39. The least common multiple (LCM) of 29 and 39 is 1131, so we'll multiply the first term by (39/39) and the second term by (29/29):

= ((-50/29) * (39/39)x + (140/39)x) + (25y - 105y) + (-45 + 56 - 42)

= (-1950/1131x + 5460/1131x) + (-80y) + (-31)

Now, let's combine the x terms:

= (-1950/1131x + 5460/1131x) + (-80y) + (-31)

= (3510/1131x) + (-80y) + (-31)

Finally, we can simplify further if needed or convert the expression into decimal form.
