How do I solve this equation?

..-x
[-------- - 5=2x]3
..3

-x-15=6x
-x-6x=15
-7x=15
x=-15/7 answer//

-X/3 - 5 = 2x
or, -x - 15 = 6x [multiplied by 3]
or, -15 = 6x + x
or, 7x = -15
x = -15/7

(-x / 3) - 5 = 2x

Multiply 3 on all numbers to get rid of the fraction.

-x - 15 = 6x
+x +x
-15 = 7x
7x = -15
/7 /7
x = -15/7

-x/3 - 5 = 2x
-5 = 2x + x/3
2x + x/3 = -5
x(2 + 1/3) = -5
x = -5/(2 + 1/3)
x = -5/(6/3 + 1/3)
x = -5/(7/3)
x = -5(3/7)
x = -15/7

- x - 15 = 6 x

- 15 = 7 x

x = - 15 / 7

Mr tyrone. we need to take like terms on one side and you will change the sign of the term when you change sides , also you should know a = b implies b = a .

-x/3 - 5 = 2x means -5 = 2x+ x/3 = 7x/3
now x = -5 * 3/7= -15/7

if you didnt understand this, lets try another method to clarify

we have the equation -x/3 - 5 = 2x let us add x/3 to both sides

-x/3 + x/3 -5 = 2x +x/3 which is same as - 5 = x( 2 + 1/3) pr -5 = 7x/3 ( the two x/3 and -x/3 get cancelled - thats why we added the term)

now we have 7x/3 = -5 how do we find x , we need to get rid of the term 7/3 now how do we do that , let us multiply both sides by 3/7 we know 7/3 * 3/7 = 1

7x/3 * 3/7 = -5 * 3/7 or x = -15/7

hope this is clear. all the best

(- x/3) - 5 = 2x. Solve for x.

Multiply all terms by 3 to cancel out the denominator.

- x - 15 = 6x. Add x to both sides.

- 15 = 7x. Divide both sides by 7.

x = - 15/7. Answer

-X/3 - 5 = 2x

=>-x/3 - 2x = 5

=>x/3 - 6x/3 = 5

=>x- 6x = 5 * 3

=> -7x = 15

=>x = -15/7

0

-x/3 - 5 = 2x (times by 3)
-x - 15 = 6x (plus by x)
-15 = 7x (divide by 5)
x = -15/7
