Question

-3x+9=5x-23
Solve for x

Answer 1

Solution Steps:

-3x = 5x - 14

-8x = -14

x = 1.75

Answer 2

The solution for -3x + 9 = 5x – 23 is 4

Solution:

From question, given that -3x + 9 = 5x – 23

By moving 5x from right side to left side, we get the above equation as,

-3x – 5x + 9 = – 23

By combining -3x and -5x,

We know that addition of -3x and -5x yields -8x. hence the above equation becomes,

-8x + 9 = -23

By moving 9 from left side to right side, the above equation becomes,

-8x = -23 -9

-8x = -32

Negative sign on both sides cancels out each other.

8x = 32

`x = (32)/(8) = 4`

hence the solution of -3x + 9 = 5x – 23 is 4
