Question

in the equation: -4x + 12 = -11 what is the value x?

Answer 1

Remove the +12 from the equation. Do so by subtracting it from both sides.
-4x + 12 - 12 = -11 - 12
-4x = -11 - 12

After you subtract 12 from -11, divide that new number by four, leaving you with x = your answer.

Answer 2

so x = 5.75?

Answer 3

What you're trying to do is isolate x.

You do this by taking out all other numbers on the side of the equation that x is on.

So, if you want to take out positive 12, subtract it; BUT, what you do on one side, you have to do to the other side.

Answer 4

yea you're right. good job :)

Answer 5

oh okay so : -4x = -23

Answer 6

Indubitably.

Answer 7

okay thanks i just wanted to make sure

Answer 8

yea, but then simplify by dividing by 4, leaving you just with "x"

Answer 9

and u also dived the other side by -4 an u get 5.75.

x= 5.75

Answer 10
