What is the value of x in the equation −x = 3 − 4x + 6?

−9
−3
3
9

Answer 1

-6 + x = -3
x = -3 + 6
x = 3 <==

-x = 3 - 4x + 6
-x + 4x = 3 + 6
3x = 9
x = 9/3
x = 3 <==

Answer 2

Value of x in −6 + x = −3 is: 3

Value of x in −x = 3 − 4x + 6 is: 3

Explanation:

We have to solve for x

1. −6 + x = −3

Adding both sides by 6, we get

x= -3+6

x=3

2. −x = 3 − 4x + 6

Adding by 4x on both sides

-x+4x=3+6

3x=9

Dividing both sides by 3, we get

x=3
