solve for x?

Question

solve for x: 3.3 - x =3(x - 1.7)

Answer 1

3.3 - x = 3(x - 1.7)

First you simplify the part on the right with the distributive prop.

3.3 - x = 3x - 5.1

Second you add the lowest X, which is - x to both sides

3.3 - x + x = 3x + x - 5.1
3.3 = 4x - 5.1

Then add the 5.1 to make problem easir to solve

3.3 + 5.1 = 4x - 5.1 + 5.1

8.4 = 4x

Then divide.

8.4/4 = 2.1

X = 2.1

Answer 2

3.3 - x =3(x - 1.7)
3.3 -x=3x - 5.1
3.3+5.1=3x+x
8.4=4x
8.4/4=x
2.1=x

Answer 3

3.3 - x = 3x - 3*1.7

next, get all the x's on one side of the = sign, all terms without x's on the other

3.3 + 5.1 = 3x + x

you should be able to take it from here....

good luck.

Answer 4

3.3 - x = 3(x - 1.7)
- x = -3.3 + 3( x - 1.7)
- x = -3.3 + 3x - 5.1
- x - 3x = -3.3 - 5.1
- 4x = -8.4
- x = - 2.1
x = 2.1

Answer 5

3.3 - x =3(x - 1.7)
3.3 - x = 3x - 5.1
3.3 + 5.1 = 3x + x
8.4 = 4x
x = 2.1

Answer 6

3.3 - x = 3(x - 1.7)
3.3 - x = 3x - 5.1
-3x - x = -5.1 - 3.3
-4x = -8.4
x = -8.4/-4
x = 2.1

Answer 7

3.3 - x =3(x - 1.7)
3.3 - x =3x - 5.1
4x = 8.4

x = 2.1

Answer 8

first get rid of the brackets:
3.3-x = 3x-5.1

then get x to one side (here by adding +x to both sides):
3.3 = 4x-5.1

now let x stand alone on one side (adding +5.1 to both sides):
8.4 = 4x

and finally you get:
2.1 = x

Answer 9

3.3 - x = 3(x-1.7)
3.3 -x = 3x - (1.7)(3)
3.3 - x = 3x -5.1
3.3 -x -3x = -5.1
3.3 -4x = -5.1
-4x = -5.1 -3.3
-4x = -8.4
x = -8.4/-4
x= 2.1

Answer 10

Simplify to 4 x = 8.4
x = 2.1

3.3 -2.1 = 3(2.1 - 1.7)
1.2=1.2
