What is the value of x in the equation 0.2(x + 1) + 0.5x = –0.3(x – 4)?

 x=1

Step-by-step explanation:

0.2(x+1) + 0.5x= -0.3(x-4)

Distribute the 0.2 to the parentheses

0.2x + 0.2 + 0.5= -0.3(x-4)

Distribute the -0.3 to the parentheses

0.2x + 0.2 + 0.5= -0.3x + 1.2

Combine Like Terms

0.7x + 0.2= -0.3x + 1.2

Move the variable to one side

(i picked to move the -0.3 because it is negative but you should be able to do it either way)     x + 0.2 = 1.2

Use subtraction property of equality to get the variable by itself

x + 0.2 = 1.2

   -0.2     -0.2

x= 1

Check it by plugging 1 wherever x appears in the original equation and solve it normally.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
