Question

Find the value of x that makes the statement true.

3/5x-5+x-4 =-1

A. -5
B. 5
C. 7
D. -7

Answer 1

B

Explanation:

5

Answer 2

Explanation:

I guess the equation is

(3/5)x - 5 + x - 4 = -1

or is it

(3/5)(x - 5) + x - 4 = -1 ?

or is it

3/(5x) - 5 + x - 4 = -1 ?

or is it

3/(5x - 5) + x - 4 = -1 ?

or even something else ?

the way you wrote it, following the rules strictly, it would be the first option I listed.

so, it is

(3/5)x - 5 + x - 4 = -1

3x/5 - 5 + x - 4 = -1

3x/5 -9 + x = -1

3x/5 + x = 8

3x + 5x = 40

8x = 40

x = 5, and B would be the right answer.
