Question

-.5x + 3 = -x+7? A.) 1/2 B.) 8 C.)-8 D.) 2

Answer 1

-5x+3=-x+7
=>-5x+x=7-3
=>-4x=4
=>x=-1

Answer 2

its 1/2 not 5. sorry!

Answer 3

-.5x + 3 = -x+7
Add -.5x to both sides

-.5x + 3 = -x+7
+.5x +.5x
--------------
3= -.5x + 7

Subtract 7 from both sides

3= -.5x + 7
-7 -7
-------------
-4 = -.5x

Divide by -.5 on both sides

-4/-.5 = -.5x/-.5

-4/-.5=x

8=x

So..this time you try and solve the equation.

Answer 14

ok!

Answer 15

:)
Post your work on here then k?

Answer 16

ok!

Answer 17

2x + 12 - 10 = 12 + 4x - 4
+10 +10
2x + 12 = 22 + 4x - 4
-12 -12
2x = 34 + 4x -4
-4 -4
-2x = 34 -4
-2x = 30

x = -15?

Answer 18

?

Answer 19

Not quite..
Lemme show u my work.\, then try to see where you messed up

Answer 20

ok

Answer 21

2(x+6)-10 = 12+ 4(x-1)
Distribute the 2 and 4 on their own sides
2x+12 -10 = 12 +4x -4
Add/Subtract like terms on their own sides of the equal sign
2x + 2 = 8 +4x
Subtract 2x from both sides
2x + 2 = 8 +4x
-2x 2x
--------------------
2= 8 + 2x
Subtract 8 from both sides
2= 8 + 2x
-8 -8
--------------
-6= 2x
Divide by 2 on both sides
-6/2=2x/2
-3 = x

Answer 22
