Question

6 + 8/10x = 9/10x what is x?

Answer 1

6+8/10x=9/10x
subtract 8/10x from both sides
6=1/10x
multiply each side by 10
60=x

Answer 2

`\sf 6+ (8)/(10) x= (9)/(10) x`
Subtract
`(8)/(10) x` from both sides


`\sf 6+ (8)/(10) x - (8)/(10) x= (9)/(10) x- (8)/(10) x`

Simplify:

`\sf 6 = (1)/(10)x`

Multiply 10 on both sides:

`\sf 6 * 10= (1)/(10)x * 10`

Simplify

`\sf 60= x`

So your answer is x=60. :)
