Question

5*(2х-6)+7*(5х+2)-10*(4х-9)=?

Answer 1

Ответ:

10x-30+35x+14-40x+90=0

5x=74

x=74/5

x=14,8

Answer 2

To solve the equation, first distribute the numbers outside the parentheses:

5*(2x - 6) + 7*(5x + 2) - 10*(4x - 9)

Now, apply the distributive property (multiply each term inside the parentheses by the number outside):

= 10x - 30 + 35x + 14 - 40x + 90

Next, combine like terms (terms with the same variable 'x'):

= (10x + 35x - 40x) + (-30 + 14 + 90)

= 5x + 74

So, the result of the equation is 5x + 74.
