-8(3x+5)+6(4x-6)+x при x=-5,4

(сначало сократим наш пример, чтобы было легче решать )

-8(3x+5)+6(4x-6)+x=-24-40+24х-36+х=-64-11х; при х=-5,4; -64-11*(-5,4)=-64+59,4=-4,6

Answer 2

Ответ:

-24x-40+20x-36+x=

-3x-76=0

-3×(-5,4)-76=0

Answer 3

To solve the given equation, let's substitute the value of x = -5.4 into the equation and simplify it step by step.

Given equation: -8(3x+5) + 6(4x-6) + x

Step 1: Substitute x = -5.4 into the equation. -8(3(-5.4)+5) + 6(4(-5.4)-6) + (-5.4)

Step 2: Simplify the equation using the order of operations (PEMDAS/BODMAS). -8(-16.2+5) + 6(-21.6-6) - 5.4

Step 3: Continue simplifying. -8(-11.2) + 6(-27.6) - 5.4

Step 4: Multiply the numbers inside the parentheses. 89.6 + (-165.6) - 5.4

Step 5: Add and subtract the numbers. (89.6 - 165.6) - 5.4

Step 6: Simplify further. -76 - 5.4

Step 7: Subtract the numbers. -81.4

Therefore, when x = -5.4, the value of the given expression -8(3x+5) + 6(4x-6) + x is -81.4.
