Answer:

2.5+7.5+-10n+-20

Step-by-step explanation:

Multiply everything on the inside by the number on the outside and put it together with addition signs.

-2.5(-3+4n+8)

-2.5*-3=7.5

-2.5(7.5+4n+8)

-2.5*4= -10

-2.5(7.5+-10n+8)

-2.5*8=-20

-2.5+7.5+-10n+-20

Answer:

x = 4

Step-by-step explanation:

The equation comes out to be:

3x + 11 = 5x + 3

Move the <u>variables</u> to the left-hand side and change its sign

And move the <u>constant</u> to the right-hand side and change its sign:

3x - 5x = 3 - 11

Combine like terms to get:

-2x = -8

Isolate x by dividing -2 on both sides:

-2x/-2 = -8/-2

x = 4
