Answer:

x = 3

Step-by-step explanation:

-4x  + 2x - 5 = -11

Combine like terms

-2x - 5 = -11

Add 5 to both sides

-2x = -11 + 5

-2x = -6

Divide both sides by (-2)

x = -6/-2

x = 3

tia_tia [17]

Answer:

1010

Step-by-step explanation:

There are a whole class of questions that rely on the method to this one.

First add up what you know

1270 + 1150 + 870 + 1450 = 4740

Now add on the 5th month (which you don't know. Call it x)

4740 + x

Divide by 5

(4740 + x)/5 = 1150 and that is your equation    

Solution

Multiply both sides by 5

5*(4740 + x) / 5 = 1150 * 5

4740 + x = 5750

Subtract 4740 from both sides

4740 - 4740 + x = 5750 - 4740

x = 1010

Which seems kind of low, but that's what the numbers come to.
